Name at birth: Lisa Olivia Munn
Olivia Munn began hosting Attack of the Show! in 2006 and has since carved out a niche as a sexy "geek" girl with a penchant for crude language and low humor. She grew up in Oklahoma and Japan, and she began her career as a model. She had early breaks in cable television, including a recurring role in the TV series Beyond the Break (2006-07), but most of her fans and fame came from her fast-talking commentary on entertainment technology on the G4 channel's Attack of the Show!. Her success there led to a career that puts her somewhere between Jenny McCarthy and Sarah Silverman -- a hot babe in a bikini who can crack crude jokes just like one of the guys. She made her feature film debut in Big Stan (2007), and has since appeared in Insanitarium (2008), Date Night (2009, starring Tina Fey and Steve Carell) and Iron Man 2 (2009, starring Robert Downey, Jr.). While still hosting her G4 cable show, she landed a gig in 2010 on The Daily Show as a sometime "correspondent," and a co-starring role in the NBC sitcom Perfect Couples.
