She's your American Idol, but she's no longer his girlfriend. Carrie Underwood and Chace Crawford have ended their eight-month romance, sources tell Us. During that time, says the glossy, Underwood had spent Thanksgiving as well as part of her Christmas break with Crawford's relatives.

Has Crawford already moved on, perhaps in a different direction? Earlier today, former NSYNCer JC Chasez called Chace "a super nice guy" but shot down a rumor that he and the Gossip Girl guy are involved. "For the record, we're both straight," he told Kiss-FM 104.7. "We're not dating." - MWM
