Boom! TMZ reports that Kara DioGuardi has been fired from American Idol, the show will return to a three-judges format, and that sitting at the table next year will be Randy Jackson, Jennifer Lopez, and ... Aerosmith's Steven Tyler! (Kara may still get called back if Lopez backs out, but this seems unlikely since what else does J.Lo have to do these days?) Is the recently rehabbed Tyler qualified to replace Simon Cowell? He is certainly good at being mean to the other members of Aerosmith. Developing!
