American Idol, what are you doing? TMZ reported Friday that Randy Jackson will no longer be judging the show, although he will remain on as a mentor. What does mentoring mean? No one is sure, but apparently Idol’s producers feel Jackson is the glue that holds the show together. Sources connected to the show said that the Nicki Minaj deal is “99 percent done,” but the show is searching for a fourth judge to fill the table. Mariah Carey has already signed on to judge, and producers reportedly wanted Diddy or Kanye West for the role, although that has apparently fallen through.
