JC Chasez Gossip

Chace Crawford and Carrie Underwood recently broke up.

The celebrity gossip du jour was that another man may have come between them. And that it was Chace who was involved with that man.

But alas, it looks like that was just a rumor.

Former NSYNC singer, JC Chasez, 31, debunked Internet rumors linking him to the Gossip Girl star Chace Crawford, 22, on Kiss-FM 104.7 on Wednesday.

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

JC Chasez â€" who called Chace Crawford a "super nice guy" â€" said he understands why people may think they're an item.

"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, then I'm having an affair," Chasez added. "So now, 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."

Crawford and the Gossip Girl cast return with new episodes April 21.
