It's official: David Cook and Kimberly Caldwell are no longer an item.

Cook, the winner of American Idol season seven, and Caldwell, a season two contestant, have broken up amicably, says Caldwell's rep.

"Kimberly and David ended their relationship just before the holidays. The couple remain good friends and being very private people, appreciate their privacy at this time."

Cook's rep also confirmed the split.
