Ellen DeGeneres is leaving "American Idol" after one season as a judge for the hit Fox TV singing contest.
A person close to the show says DeGeneres won't return for the 10th season, which gives "American Idol" two vacancies on its judging panel. Fox has yet to announce a replacement for Simon Cowell, who left at the end of last season to start a new talent show for the network.
The person, who lacked authority to comment publicly on DeGeneres, spoke on condition of anonymity.
With "American Idol" facing ratings erosion, the comedian-talk show host's exit gives Fox the chance to make a fresh start with a revamped judging panel. The show returns in January.
