Paris Hilton in Blue

Paris Hilton was born on February 17th, 1981, to Rick and Kathy Hilton, making her the great-granddaughter of Conrad Hilton, founder of the Hilton hotels and source of the family fortune -- estimated at $300 million. Her grandfather, Conrad "Nicky" Hilton, Jr., also brought some notoriety to the family, as he was the first of Elizabeth Taylor's many ex-husbands. Paris' younger sister, Nicky (born in 1983), shares the throne as co-heiress of the Hilton empire.

"Paris the Heiress" is first-born in the latest generation of the Hilton family (of swanky hotel fame). Fat trust fund aside, she is also known for being a high-society party girl, part-time model, part-time singer, and quasi-actress. Her most notable roles were playing herself on the reality show The Simple Life with Nicole Ritchie, as well as starring in the horror flick House of Wax (2005). She also released her debut self-titled album in 2006. Oh yes, and who could forget the craziness surrounding her June 2007 arrest for driving on a suspended license? Probably no one - it consumed the news (and the world) for what seemed like months.
