All those on-air fat jokes apparently took a toll on American Idol's Randy Jackson. According to Inside Edition, the portly Idol judge recently underwent gastric bypass surgery in an attempt to lose weight. (That explains why he was MIA at Saturday's TCA Awards. What's your excuse, Simon?) In a statement, Jackson confirmed that he has "taken serious steps to improve my health... so I may appear lighter very soon. I want to resume my Speedo modeling career." Sounds like someone's been taking classes at the Paula Abdul School of Joke Writing.
