Report: Chace Crawford Cheats on Carrie Underwood

This piece of celebrity gossip would fit right in on an episode of Gossip Girl. It appears that American Idol winner Carrie Underwood is single again - and the reason is the wandering eye of her most recent boyfriend, Chace Crawford.

Carrie Underwood and Chace Crawford have been spotted together on numerous occasions this fall, and have smiled and gushed about each other in interviews.

But, according to the New York Post, things unraveled because several weeks ago, Crawford was seen making out with some blonde - who wasn't Carrie Underwood.

Carrie Underwood may have to act out some of the scenes her "Before He Cheats" music video if these rumors of Chace Crawford's recent cheating are proven true.

Sources suggest this mystery blonde may have been Katrina Bowden.

Then, last Wednesday night at New York City's Beatrice Inn, Chace and his cute Gossip Girl co-star, Leighton Meester, were seen sucking face - and this didn't involve a scene for their CW series, on which they are boyfriend and girlfriend.

THE HOLLYWOOD GOSSIP NOTE: That would be the same Big Apple locale Heath Ledger allegedly bagged Lindsay Lohan at. That's all we've got.

We'll have more on this story as it develops. All we have to say for now is that we are here if you need us, Carrie. You just need a nice, normal guy who will commit to you... not these Chace Crawford / Tony Romo players. Jerks.
