Nigel Lythgoe, Ken Warwick

5 changes American Idol needs to make in Season 13

The move would add to the exodus of the show's famous talent. Judges Mariah Carey, Randy Jackson, and Nicki Minaj have all announced they won't be back next year. Fox's reality TV brain-trust Mike Darnell stepped down May 24, casting a shadow of doubt over where the show would go next. High-profile Idol alums -- including Jennifer Hudson and Kelly Clarkson -- have been rumored to join the judges' table in 2014.

Lythgoe and Warwick helped start American Idol in 2002.
