Mary J. Blige To Guest Judge On American Idol

Mary J. Blige is the latest star to be added to the judging panel for American Idol!

Mary will meet up with Simon Cowell, Randy Jackson and Kara Kara DioGuardi in Atlanta for auditions, according to People Magazine.

Mary will join Victoria Beckham and Katy Perry as other guest judges, and at the rate Fox is going, we wouldn't be surprised if they announced another fill-in judge next week!
