Gia Mantegna plays Vanessa. New York-born and LA-raised, Gia grew up around theater and acting -- she was born while her dad, Joe Mantegna, was busy filming "The Godfather: Part III."

She shot her first film when she was 13 and has since appeared in "13 Going on 30," "Unaccompanied Minors ... more," and in "In The Land of Women."

You might have also seen her playing Patty on "The Secret Life of the American Teenager."

Gia plays piano and drums and is into photography.
