Chace Crawford and Carrie Underwood recently broke up, and one of the more ridiculous rumors spawned by that fact was that he and friend JC Chasez are, well, more than just friends.

Chasez says it's simply not the case.

The former NSYNC singer, 31, debunked Internet rumors linking him to the Gossip Girl star, 22, on Kiss-FM 104.7 on Wednesday.

"For the record, we're both straight," Chasez said. "We're not dating."

JC Chasez — who called Chace Crawford a "super nice guy" — said he understands why some gossip readers may think they're an item.

JC Chasez and Chace Crawford: Friends, but not more.

"The only time people usually see us together is in some type of photograph, so they just assume that it's like that," he said. "If I'm dating a girl and I'm standing next to another girl, I'm having an affair."

"Since there hasn't been any of that smoke out there, if I'm hanging out with a guy, they're going to make up a rumor. It's just stupid."

There is a gay character on Gossip Girl, however, and he will be revealed when the show returns.

Could it be Nate Archibald? Wouldn't that be ironic.
