As had been rumored for a while, Mariah Carey and Nicki Minaj have both publicly confirmed that they are leaving 'American Idol' after this season, following the announcement that Randy Jackson was also retiring. This leaves Keith Urban as the last judge standing, though perhaps not for long.
'American Idol' used to be the hottest show on television, but after 13 years, it's starting to show its age. The show's ratings have slipped from regularly having 30 million viewers to now somewhere around 11 million. And though the show has had some different judges over the course of its run, it's now looking to ditch all four current judges to have a fresh face for season 13.
