J. Lo joined Steven Tyler on the judging table after replacements were needed for Simon Cowell, Kara DioGuardi and Ellen DeGeneres left the show. She served as a judge for seasons 10 and 11 and recently announced she was leaving the show. Everyone assumed she left because of salary negotiations, but she told Ryan Seacrest on his talk show the opposite. The star said, "I could do Idol for the rest of my life, but that would be giving up a bunch of other things... I have my movies and my music and my this and my that. It all kind of worked together for a while, but then it gets more complicated."
