Hilton was born in New York City, New York, to Richard, a businessman, and his wife, Kathy Hilton (née Avanzino), a socialite and actress. She is the oldest of four children: she has one sister, Nicholai Olivia "Nicky" Hilton (b. 1983) and two brothers, Barron Nicholas Hilton II (b. 1989) and Conrad Hughes Hilton III (b. 1994). Hilton is of Norwegian, German, English, Irish, and Italian ancestry. She is a niece of two child star of the 1970s, Kim and Kyle Richards.

Hilton moved between several exclusive homes in her youth, including a suite in the Waldorf-Astoria Hotel in Manhattan, Beverly Hills, and the Hamptons. As a child she was good friends with other socialites, including Nicole Richie and Kim Kardashian. She attended her freshman year of high school at the Marywood-Palm Valley School in Rancho Mirage, California followed by a short time at Convent of the Sacred Heart (which she attended with Lady Gaga) and the Dwight School in New York for her sophomore and junior years. She was then transferred to the Canterbury Boarding School, in New Milford, Connecticut where she was a member of the ice hockey team. Paris Hilton was high-school hockey 'sensation' In February 1999, she was expelled for violating school rules and later earned her GED.

In December 2007, Hilton's grandfather Barron Hilton pledged 97 percent of his estate to a charitable organization founded by his father, the Conrad N. Hilton Foundation. An immediate pledge of $1.2 billion was made, with a further $1.1 billion due after his death. He cited his father's actions as the motivation for his pledge. According to reports, the potential inheritance of his grandchildren is sharply diminished.

2001—present: As a model

Hilton began modeling as a child, initially at charity events. When she was 19, she signed with Donald Trump's modeling agency, T Management. Hilton has also worked with Ford Models in New York, Models 1 Agency in London, Nous Model Management in Los Angeles, and Premier Model Management in London. She has appeared in numerous advertising campaigns, including Iceberg Vodka, GUESS, Tommy Hilfiger, Christian Dior, and Marciano. In 2001, Hilton began to develop a reputation as a socialite, being identified as "New York's leading It Girl" whose fame was beginning to "extend beyond the New York tabloids". She has appeared in several magazines, including the April 2004 issue of Maxim.

2003—present: As an actress

Hilton has made cameo appearances in several films, notably Zoolander, Wonderland, and The Cat In The Hat. Hilton co-starred with her friend Nicole Richie in the Fox reality series The Simple Life, which premiered on December 2, 2003. The Simple Life ran for three seasons on Fox. The show was cancelled by Fox after a dispute between Hilton and Richie, but it was subsequently aired by E! Entertainment Television for the fourth and fifth seasons. Despite talks of a sixth season, the series finished its run at the end of the fifth season. In March 2008, it was reported that Hilton would star in a new MTV reality series tentatively titled Paris Hilton's My New BFF, about her looking for a new best friend. The series premiered on September 30, 2008.

She landed minor and supporting roles in the feature films Nine Lives, Raising Helen, The Hillz, and House of Wax. Her role as Paige Edwards in House of Wax won the Teen Choice Award for "Best Scream" and earned her a nomination for "Choice Breakout Performance  — Female". (It also won her the 2005 Razzie for "Worst Supporting Actress" at the 2005 Golden Raspberry Awards.) She also earned a nomination for "Best Frightened Performance" at the 2006 MTV Movie Awards. She landed her first lead roles in 2006 with the straight-to-DVD releases National Lampoon's Pledge This! and Bottoms Up. She plays the Hottie in the box office bomb romantic comedy The Hottie and the Nottie, released in 2008. She also had a minor cameo appearance as herself in An American Carol.

More recently, Hilton plays Amber Sweet, the surgery- and painkiller-addicted daughter of a biotech magnate in the goth/rock musical Repo! The Genetic Opera. Critics have responded positively to her performance in the film, in which she sings and acts. In an interview Repo! director Darren Lynn Bousman revealed that he had originally refused to audition Hilton for the role of Amber Sweet. "I broke down," says Bousman, "and I met with her, and immediately she charmed everyone in the room." In the same interview, Bousman also revealed that Hilton was so keen to get the part that she had the script smuggled in to her during her much publicized stint in a Los Angeles jail, and used her time inside to work on her role.

Hilton has also guest-starred in episodes of the popular tv-show The O.C., The George Lopez Show, Las Vegas, American Dreams, Dogg After Dark, and Veronica Mars. Furthermore, she appeared in several music videos, including "It Girl" by John Oates and "Just Lose It" by Eminem.

Hilton guest-starred in the fifth episode of Supernatural's fifth season. "Paris Hilton is playing a demonic creature that takes the form of... Paris Hilton," creator and executive producer Eric Kripke said in a statement. "It'll be a fun, irreverent episode and we here at Supernatural are thrilled that Paris agreed to do it."

2004—present: As a singer

Hilton founded Heiress Records, a sub-label of Warner Bros. Records, in 2004 and released her self-titled debut album, Paris, under that label on August 22, 2006. Although the album reached number six on the Billboard 200 for a week, its total sales volume has been low — but the first single "Stars Are Blind" was a top ten hit in 17 countries. Allmusic commented that the album was "more fun than anything released by Britney Spears or Jessica Simpson, and a lot fresher, too." As a whole, critical reception was mixed. Paris Hilton can also be heard singing on the soundtrack to the musical Repo! The Genetic Opera. In an interview, the director, Darren Lynn Bousman, praised her vocal skills. When talking about Paris' vocal audition process for the role, Bouseman said, "We gave her some music and said, 'You have one day to come back and perform this.' She came back the next day, memorized everything, was pitch-perfect, I mean she was awesome."

On July 16, 2007, Hilton confirmed that she was working on a new album with producer Scott Storch. In a recent interview with MTV, Hilton decided that her second album is going to be a dance album. She stated that she "loves Bob Sinclar" and wants to create dance-music vibe. Hilton has installed a professional recording studio in her house to work on the album. On September 30, 2008, Hilton premiered her song "My BFF" on KIIS-FM with host Ryan Seacrest. It is the first single from her as yet untitled second studio album and the theme song of her show Paris Hilton's My New BFF. Hilton stated that she finished working on the album. A second song "Paris For President" was released along with a music video late October 2008.

For her second studio album, she has confirmed six tracks: "Jailhouse Baby", "Platinum Blonde", "Crave" and "My BFF", "Paris For President", and "Girl Tax", Paris’ new single ‘My BFF,’ other songs: ‘Paris for President,’ ‘Jailhouse baby’ — Paris Hilton Gossip "My BFF" and "Paris For President" were released in 2008 as the first two singles. In November 2008, Hilton talked with Entertainment Weekly backstage at the American Music Awards and she told them that she has finished her second album, and "wrote all the songs". The album is featuring production by Mike Green who worked with the bands Paramore and The Matches. Paris Hilton: I've finished my second album | EW.com In December 2008, she was looking for a label to release her album, she told Entertainment Weekly. "I'm not sure which label I'm doing it with," she said. "I'm figuring it out right now." Later that month she stated her intention to release her album under her own record label Heiress Records.

Hilton posted on Twitter that she filmed a music video for the first single, and confirmed in a magazine interview that the album is complete.

2004—06: As an author

In the autumn of 2004, Hilton released an autobiographical book, A Tongue-in-Chic Peek Behind the Pose, co-written by Merle Ginsberg, which includes full color photographs of her and her advice on life as an heiress. Hilton reportedly received a $100,000 advance payment for this book. Some in the media panned the writing as amateurish, and the book was parodied by Robert Mundell on The Late Show with David Letterman. The book became a New York Times bestseller. Hilton followed it up with a designer diary, also with Ginsberg, called Confess It All to Me.

In September 2009, Hilton's quote: "Dress cute wherever you go, life is too short to blend in" has been added to The Oxford Dictionary of Quotations.

She denied proclaiming herself as the "iconic blonde of the decade" such as Diana, Princess of Wales, and Marilyn Monroe in the May 2007 issue of Harper's Bazaar. She appeared in the 2007 Guinness World Records as the world's "Most Overrated Celebrity". In a poll conducted by the Associated Press and AOL, Hilton was voted the second "Worst Celebrity Role Model of 2006", behind Britney Spears. Critics suggest that Hilton epitomizes the title of famous for being famous; echoing that sentiment, the Associated Press conducted what they called an experiment in February 2007, trying not to report on Hilton for a whole week.

On August 6, 2008 Hilton appeared in a 1 minute 50 second long video online, "Paris Hilton Responds to McCain Ad", directed by Adam McKay and posted on the Funny or Die website. The video featured Hilton in a parody advertisement, and was made in response to a television campaign advert "Celeb", by the 2008 John McCain presidential campaign. In Celeb, McCain briefly compared his rival Barack Obama to that of celebrities such as Hilton and Britney Spears, going on to question his readiness to lead and criticize his energy policy.

In what The Washington Post opined "might just be her best acting role yet," Hilton appears in the video wearing a leopard print swimsuit. She starts out by suggesting that her personal mention by McCain means that she must now be a candidate in the presidential race, and goes on to mock McCain, and critique the expected qualities and lifestyle of a celebrity in comparison to that of a US president. In a 30 second segment, in the style of an academic speaker, Paris compares and contrasts the policies of McCain and Obama for solving the US energy crisis, and goes on to propose a 'compromise solution' combining elements of both.

The video received 7 million views in two days garnering worldwide press coverage, and drew both written and verbal media response from both campaigns. The merits and drawbacks of the 'Paris compromise solution' with regard to energy policy, as well as its contrast to the adversarial political campaigns, generated multiple comments from US political commentators, as well as Speaker of the House Nancy Pelosi and Congressman Michael Burgess.

Continuing the spoof campaign, in October Hilton featured in a second parody video posted on Funny or Die, the 2 minute 20 second long "Paris Hilton Gets Presidential with Martin Sheen", alongside Hollywood actor Martin Sheen, with his son, actor Charlie Sheen, appearing in a cameo role. Hilton, heavily made up and in a green evening dress, interviews Martin Sheen in a kitchen, discussing various political issues, seeking his advice from his days playing a fictional President on The West Wing.

Hilton helped design a collection of purses for Japanese label Samantha Thavasa, and also a jewelry line for Amazon.com.

In 2004, Hilton was involved in the creation of a perfume line by Parlux Fragrances. Originally set to be a small release, high demand led to a wider release before December 2004. The launch was followed by a 47 percent increase in sales of Parlux products, predominantly due to sales of the Hilton-branded perfume. After the success of Hilton's perfume, Parlux Fragrances released several more perfumes with her name, including fragrances for men. Hilton launched a new fragrance in October 2007, called Can Can. This is her fourth women's fragrance after Paris Hilton, Just Me, and Heiress. During the month of November 2008, Hilton released her fifth fragrance for women called, Fairy Dust. In July 2009, her sixth fragrance for women Siren was launched.

In January 2007, Hilton released the DreamCatchers line of hair extensions in partnership with Hair Tech International. In early August 2007, Hilton signed a licensing agreement with Antebi for a signature footwear line, "Paris Hilton Footware", featuring stilettos, platforms, flats, wedges, and a sports collection, expected to reach stores in 2008. In mid August 2007, Hilton launched a line of tops, dresses, coats, and jeans at Kitson boutique in Los Angeles.

In 2005, Hilton lent her name to a chain of nightclubs owned by Fred Khalilian and known as Club Paris. This association ended in January 2007 after she had failed to attend several scheduled promotional appearances.

In December 2007, Hilton posed nude, covered in gold paint, to promote "Rich Prosecco", a canned version of an Italian sparkling wine. She also traveled to Germany to promote the drink, appearing in various print ads for the product.

In February 2010, Hilton participates in an advertising campaign for the launch of the Brazilian beer Devassa. As part of the campaign, Hilton will also join the carnival of Rio de Janeiro in the cabin of the brewery.

Hilton was engaged to fashion model Jason Shaw from mid-2002 to early 2003. In 2003—2004 she had a relationship with singer Nick Carter. Later she was engaged to Greek shipping heir Paris Latsis, from May 29, 2005 to November 2005. Thereafter, she began dating another Greek shipping heir, Stavros Niarchos III, before breaking up in May 2006. In early 2008, she was spotted with Good Charlotte guitarist Benji Madden and in May, Hilton announced her intention to marry Madden during an interview with television talk-show host David Letterman. The two broke up in November 2008, and "remain very good friends". Paris Hilton and Benji Madden Split Up — Breakups, Benji Madden, Paris Hilton : People.com She began dating The Hills star Doug Reinhardt in February 2009; Hilton has also referred to her intention to marry Reinhardt, saying "He's gonna be my husband." The couple broke up in June 2009, only to get back together again in August of the same year. On April 13, 2010, Hilton reportedly split from Reinhardt because she was worried he was just using her to further his career. Paris Hilton and Doug Reinhardt split | Metro.co.uk

Hilton told Live with Regis and Kelly: "One-night stands are not for me. I think it's gross when you just give it up. Guys want you more, if you don't just hand it to them on a platter."

Hilton loves small dogs, and lives with a Yorkshire Terrier and a female Chihuahua named Tinkerbell among many other pets. Paris Hilton is frequently seen carrying Tinkerbell (dubbed an "accessory dog") at social events and functions, and in all five seasons of television reality show The Simple Life. In 2004, Tinkerbell "authored" a memoir, The Tinkerbell Hilton Diaries. On August 12, 2004, Tinkerbell went missing after Hilton's apartment was burgled, and a $5,000 reward was offered for her safe return. She was found six days later. By December 1, 2004, Tinkerbell was again spotted with Paris Hilton at various events. Hilton has also purchased a male Chihuahua on July 25, 2007 from Pets of Bel Air in Los Angeles. Hilton's love for man's best friend led her to create an apparel line for dogs called Little Lily by Paris Hilton, with some of the proceeds going to benefit animal rescue. "I have 17 dogs and I like to dress them, so I started designing this clothing line and it's really cute, like dresses and jeans ... everything you can imagine for humans, but for dogs," she said in an interview during Super Bowl XLII festivities. Hilton's love for her dogs led to the rumor that she wanted to be frozen with them at the Cryonics Institute, but Hilton denied the rumor on The Ellen DeGeneres Show.

A homemade sex video of Hilton and then-boyfriend Rick Salomon was leaked on the Internet in 2003, later released as the DVD 1 Night in Paris despite attempted legal action. It appeared a week prior to the premiere of The Simple Life.

On January 22, 2007, Hilton's private life was thrust into the media spotlight with the launch of ParisExposed.com, a website that features images of personal documents, video, and other material allegedly obtained when the contents of a storage locker rented by Hilton was auctioned off due to lack of a $208 payment. Paris Hilton's new sex tape | The Sun |Showbiz|Bizarre The website began charging online access to this material and received 1.2 million visitors in just over 40 hours. Among the contents were medications, diaries, photographs, contracts and love letters, as well as a video of her shot by Joe Francis of Girls Gone Wild. On February 3, 2007 Hilton obtained a temporary injunction against ParisExposed.com, closing down the website.

On February 5, 2007, CNN's Anderson Cooper 360 discussed footage obtained from the ParisExposed.com website which features Hilton using the ethnic slurs "niggers", "chink", "Jappy" and the derogatory term "faggot".

Hilton was burglarized at least five times by the Bling Ring. In most cases they were only after cash and clothes. However, during their final burglary of her home, a participant usually not present as a member of the group stole around $2 million in jewelry from her, carrying it out in one of her Louis Vuitton bags. It was only after this theft that she informed police of having been burglarized.

DUI arrest, driving violations, and jail time

In September 2006, Hilton was arrested and charged with driving under the influence of alcohol with a blood alcohol content of 0.08%, the level at which it is illegal to drive in California. Hilton's driving license was subsequently suspended in November 2006, and in January 2007 she pleaded no contest to a reckless driving charge. Her punishment was 36 months' probation and fines of about $1,500. On January 15, 2007, Hilton was pulled over for driving with a suspended license and signed a document acknowledging that she was not permitted to drive. On February 27, 2007 Hilton was caught driving 70 mph in a 35 mph zone, again with a suspended license. She also did not have her headlights on even though it was after dark. Prosecutors in the office of the Los Angeles City Attorney charged that those actions, along with the failure to enroll in a court-ordered alcohol education program, constituted a violation of the terms of her probation.

On May 4, 2007 Hilton was sentenced by Judge Michael T. Sauer to 45 days in jail for violating her probation. Initially, Hilton planned to appeal the sentence, and supported an online petition asking California governor Arnold Schwarzenegger for a pardon. The petition was created and organized on May 5, 2007 by Joshua Morales. In response, various opponents started a counter-petition to maintain the sentence. Both petitions attracted tens of thousands of signatures. Hilton later switched lawyers and dropped her plans to appeal.

Hilton was required to begin her jail term on June 5, 2007, and checked herself into the Century Regional Detention Facility, an all-female jail in Lynwood, California after attending the 2007 MTV Movie Awards on June 3, 2007. However Los Angeles County Sheriff Lee Baca signed orders on June 7, reassigning Hilton to 40 days of home confinement with an electronic monitoring device due to an unspecified medical condition. Baca commented on the release saying, "My message to those who don't like celebrities is that punishing celebrities more than the average American is not justice," contesting that under normal circumstances, Hilton would not have served any time in jail, and he added that "The special treatment, in a sense, appears to be because of her celebrity status ... She got more time in jail". On the same day that Hilton was released from jail, Judge Michael Sauer summoned her to reappear in court the following morning (June 8) as the sentencing statement had explicitly said she would serve time in jail with "No work furlough. No work release. No electronic monitoring." At the hearing he declined to be briefed by Hilton's attorney in private chambers on the nature of her condition and sent her back to jail to serve out her original 45-day sentence. Upon hearing the sentence, Hilton shouted, "It's not right!" and started screaming, requesting to hug her mother who was present in the courtroom. Concern about Hilton's condition led to her being moved to the medical wing of the Twin Towers Correctional Facility in Los Angeles, and she was moved back to the Century Regional Detention Facility in Lynwood on June 13.

While in jail, Hilton was influenced by the clergyman minister Marty Angelo: Hilton referred to starting a "new beginning" during her interview with talk show host Larry King on June 28, 2007, two days after being released from jail, and quoted from Angelo's autobiography, entitled Once Life Matters: A New Beginning. On June 9, 2007, Marty Angelo petitioned Sauer, asking to serve out the remainder of Hilton's jail sentence if the judge would release her to an alternative treatment program, but the petition was turned down.

On July 17, 2010, Hilton was detained and released after being caught in possession of cannabis at Figari airport, Corsica.

On August 28, 2010 she was arrested on suspicion of cocaine possession in Las Vegas. Initially her defence claimed that the handbag containing 0.8g of cocaine was not hers as "This purse in question was a high street brand - and by no means up to her high fashion standards.". Later she claimed some of the personal items (like cash and credit cards) from the bag acknowledging it was hers.

In order to avoid being convicted on felony, Paris Hilton pleaded guilty to two misdemeanors on September 17, 2010. Under the terms of the plea bargain, she was sentenced to one year probation, 200 hours community service, $2,000 fine and ordered to complete a drug abuse program. Clark County District Attorney David Roger said that: "If she is arrested for anything besides a minor traffic violation she will spend a year in jail. There will be no discussion. The court will have no discretion."

On September 21, 2010 Paris and her sister Nicky were stopped by immigration officers at Narita Airport, Japan because of Paris`s conviction for drug possession a day earlier: under Japan's strict anti-drug laws all people sentenced for any drug crime are in general rejected entry. The Hiltons were due to appear at a news conference in Tokyo on September 22 to promote fashion and fragrance lines . Narita officials questioned Hilton "for hours". Paris and her sister where forced to sleep over at the airport-hotel. It is unlikely that the Hiltons will be able to continue their Asian promotion tour as countries like Indonesia and Malaysia have even tougher anti-drug laws. On September 22, Japanese authorities decided not to grant Paris Hilton entrance into the country and was put on a plane back to the U.S the same day.
