Kim Kardashian

The daughter of one of O.J. Simpson's head trial lawyers, Robert Kardashian, step-daughter to Olympian Bruce Jenner and step-sister to Hills star Brody Jenner, Kardashian first hit the scene as one of Paris Hilton's party pals. Kardashian became known outside the gossip circuit when a pornographic video of her and then-boyfriend, rapper Ray J appeared on the Internet in 2006. In 2007, the blended Jenner-Kardashian family was subject of a new E! reality show called Keeping Up With the Kardashians. The show became a huge hit and led to Kardashian's December 2007 Playboy cover photo shoot – which was chronicled on the series - and her own workout video. Kardashian co-owns the Calabasas, Calif., clothing store Dash with her sisters and is currently dating New Orleans Saints NFL star Reggie Bush.
