We hoped that Paula Abdul's 'Idol' resignation - delivered to fans via Twitter - was a prank or publicity stunt, but an official statement from FOX has confirmed the news. We thought the nurturing den mother of the 'American Idol' judges' panel would be forever our girl, but now we're forced to consider the alternatives. Will the 'Idol' judge count stay at three, as it did for so many years? Or will the producers stick with last year's formula and add a fourth to join Simon Cowell, Randy Jackson and Kara DioGuardi? Just in case, we've whipped up a list of possible replacements for the divine Miss Abdul. We're here to help.
