Gossip Girl star Chace Crawford (aka Nate Archibald) caused a sensation in the realm of celebrity gossip when he started dating Carrie Underwood, and his dating life is again the center of attention...except now the rumors are that he and former N'SYNC member JC Chasez are dating!

So does Chace have a thing for musicians regardless of their gender, or is it all just gossip?  Probably the latter.  But JC recently told People magazine that he's sick of hearing the rumors.  "You know what, it's laughable the first time...I think the tenth time, it gets annoying," he told People.   He insists the two are just friends.

On the set of Gossip Girl, it looks like newcomer Michelle Trachtenberg is already getting along with the show's stars.  People.com spotted her and Blake Lively (aka Serena van der Woodsen) together in New York City on Wednesday!
