The Hilton family is a prominent Norwegian American and German American family founded by hotel magnate Conrad Hilton (1887–1979). His descendants continue to hold varying degrees of wealth and status as socialites, and some have become famous for being famous - such as great-granddaughters Paris Hilton and Nicky Hilton.

The Hilton family farmed land near Ullensaker, Norway, where relatives still live.

Kathleen Elizabeth "Kathy" Hilton (née Avanzino, later Richards; born March 13, 1959) is an American actress. She is the mother of Paris Hilton and Nicky Hilton.

Hilton was born in Whittier, California. She is the daughter of Laurence K. Avanzino (1935–1997) and Sharon Kathleen Richards (née Dugan; 1938–2002). Her parents divorced, and her mother remarried Kenneth E. Richards. Through her mother's remarriage, she has two half-sisters, actresses Kim and Kyle Richards. Hilton also has five half-siblings from her father's remarriage. Part of her maternal ancestry is Irish.

She met Hilton Hotel heir Richard Hilton at age 15; they married in 1979. Rick and Kathy Hilton have four children: daughters Paris Hilton (born 1981) and Nicholai "Nicky" Hilton (born 1983), and sons Barron Hilton II (born 1989) and Conrad Hughes Hilton III (born 1994).

Hilton attended private school, where she met singer Michael Jackson. The two remained lifelong friends, and she attended his funeral in 2009.

In 1968, when Hilton was eleven years old, she began working as an actress, retiring in 1974. Notable appearances include Bewitched, Family Affair, Happy Days, The Rockford Files, and The Dark. At the age of 17, she was one of two final candidates to play the role of Jan Brady for The Brady Bunch Hour. Eve Plumb refused to reprise her role, but Geri Reischl eventually won the role.

Paris Whitney Hilton (born February 17, 1981) is an American businesswoman, potential future heiress, producer and socialite. She is a great-granddaughter of Conrad Hilton (founder of Hilton Hotels). Born in New York City and raised in both California and New York, Hilton began a modeling career as a teenager when she was with Donald Trump's modeling agency, T Management. Her hard-partying lifestyle and rumoured short-lived relationships with Leonardo DiCaprio and Oscar de la Hoya led her to earn a position as a daily fixture in entertainment news — gossip-section Page Six, of the New York Post often includes articles about Hilton. Being known as a socialite, Hilton was hailed by the media as "New York's leading It Girl" in 2001. She went on to make cameo appeareances in Zoolander (2001), Wonderland and The Cat in the Hat (both 2003).

Hilton gained significant notoriety for her participation in a sex tape, which was released in November 2003, shortly before the premiere of the television reality series The Simple Life alongside fellow socialite and childhood best friend Nicole Richie. The show was a massive hit for the FOX network, premiering with 13 million viewers, and brought Hilton and co-star Richie to an international recognition. She then released her 2004 tongue-in-cheek autobiography called Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose, she landed a supporting role in the 2005 horror film House of Wax, and recorded the 2006 music album Paris. She starred in the reality show Paris Hilton's My New BFF which was filmed in 2008 and also resulted in a second season. The show proved to be a success and was branched out to 2009's Paris Hilton's British Best Friend and Paris Hilton’s Dubai BFF. Hilton was in 2008's Repo! The Genetic Opera, where her work gained critical acclaim.

Mario Armando Lavandeira, Jr. (born March 23, 1978), better known as Perez Hilton (a play on "Paris Hilton"), is an American blogger and television personality. His blog, Perezhilton.com (formerly PageSixSixSix.com), is known for posts covering gossip items about celebrities. He is also known for posting tabloid photographs over which he has added his own captions or "doodles." His blog has garnered negative attention for its attitude, its former "outing" of alleged closeted celebrities and its role in the increasing coverage of celebrities in all forms of media.

Hilton was born in Miami, Florida to parents from Cuba. He graduated in 1996 from Miami's Belen Jesuit Preparatory School and received his BFA in drama from New York University. In 2002, Hilton moved to Los Angeles, where he currently resides.

After graduation from New York University in 2000, and before beginning his blogging career, Hilton attempted a career as an actor. He briefly worked as a media relations assistant for LGBT rights organization GLAAD, was a freelance writer for gay publications, worked as a receptionist for NYC gay events club Urban Outings, and was briefly the managing editor of Instinct, a gay men's magazine. He says he started blogging "because it seemed easy."

River Delfín Canomanuel Viiperi (born 4 August 1991 in Ibiza, Spain) is a Spanish male model. He has been in several advertising campaigns, including those for American Eagle, Bershka, Calvin Klein,Armani Exchange and Versace for H&M.

River was born in Ibiza to a Spanish father and a Finnish mother. River's mother, Riitta Viiperi, was also a model. She saw potential in him and eventually introduced him to the world of modeling. It was not hard to convince him since he hated school, though his parents insisted he keep studying, at least until high school and soon after followed in his mother's footsteps. Though still very young, his modeling career took off very quickly and he became popular in a very short time: doing countless editorials; gracing the covers of Winq, Surface, Guapo, and Coitus; and walking for Calvin Klein shows.

River has an older sister named Luna. His hobbies include soccer, swimming and martial arts. He has his own blog called Never Back Down in which he denies common myths about the world of the male model and describes his experiences living with his roommates in their models' flat.
