Ellen DeGeneres is apparently doing good things for American Idol's ratings this season, but there are already rumours of trouble behind the scenes. This week's top 12 men and top 12 women performances didn't exactly blow us out of the water, either. Now, there are stories that Ellen is feuding with Simon Cowell and InTouch Weekly claims that her backstage list of "diva demands" is getting out of control. According to the magazine, Ellen requested a Mercedes as a signing bonus and insisted girlfriend Portia de Rossi be a guest judge among other things. Ellen has a great reputation, but there's always lots of drama at American Idol. So tell us, do you believe the rumours of diva behavior and trouble from Ellen on AI?
