American Idol judges guessing game

Today, it was announced American Idol judge Kara DioGuardi is apparently following Ellen DeGeneres and Simon Cowell by exiting the show. Now it is rumored that Jennifer Lopez has signed on as judge and Steven Tyler of Aerosmith could be next. If she is, I'll probably think twice about watching. Lopez was one of the worst guest mentors ever. Tyler would be very interesting, but I doubt he'd put all Aerosmith commitments on hold to do it. Other band members are itching to record a long awaited studio album.
