JC Chasez Calls Chace Crawford Rumors 'Annoying' | Chace Crawford, JC Chasez
Back off, gossip girls.

Former 'N Sync star JC Chasez says he's sick of online speculation that he and Chace Crawford are more than friends.

"You know what, it's laughable the first time," he told PEOPLE at the live finale of Randy Jackson Presents: America's Best Dance Crew. "I think the tenth time, it gets annoying."

Chasez and Gossip Girls star – most recently linked to Carrie Underwood – have been spotted together a lot recently (from Elton John's post-Oscar bash to the Hollywood Roosevelt Hotel this past weekend) – prompting talk of a possible romance.

"I don't care about [people's] assumptions or anything, but when people outright lie, that's wrong," said Chasez. "So I think that part of the rumor is outright stupid."

The 31-year-old – who previously dated Eva Longoria – added, "The fact of the matter is I'm a straight guy and I'm allowed to have [guy] friends."
