Kato Kaelin

Name at birth: Brian Kaelin

Kato Kaelin was a footnote in the notorious 1995 murder trial of retired football star O.J. Simpson. Simpson was accused of killing his ex-wife, Nicole Brown Simpson, and an acquaintance of hers, Ron Goldman. Kaelin, an aspiring actor, was living as a houseguest at Simpson's home the night that the murders occurred in 2004, and as such he was called to testify in the televised trial. Kaelin's sun-bleached hair and know-nothing testimony made him one of the trial's minor celebrities -- a piquant mix of California slacker dude and Hollywood hanger-on. Simpson was found not guilty, and Kaelin parlayed his fame into appearances on TV shows like The Norm Show (2001), Celebrity Boot Camp (2002) and Eye For an Eye (2005-07), and in movies including BASEketball (1998) and Dorm Daze 2 (2006).
