A huge superstar diva like Mariah Carey at the American Idol judge's table was supposed to help the show's ratings. Having her sit next to a fresher, more current diva like Nicki Minaj, and getting into catfights, made Season 12 look even more promising.
Unfortunately, despite Fox's best efforts, the show faced some of its lowest ratings yet this year... and now, after all the rumors, it's official that Mariah and Nicki won't be returning for another season.
