It’s hard to believe that American Idol judge Kara DioGuardi, who looks more like a supermodel than a songwriter, has spent so much time working behind the scenes. The daughter of a congressman, Kara got a degree in political science from Duke University, worked in advertising, and released an album with a band called Mad Doll before she built a career as a Grammy-nominated songwriter, producer, and music publisher. Over her career, Kara has worked with artists like Pink, Kelly Clarkson, and Kylie Minogue, but her biggest accomplishment to date was her season finale showdown with “bikini girl” Katrina Darrell when she ripped off her dress to reveal a skimpy black bikini of her own to roars of approval from the crowd. After showing some skin, Kara then showed some class when she gave her defeated rival a kiss on the cheek. Unfortunately it was the one on her face.
