Sexy Dancing With the Stars regular Derek Hough donned some shiny silver pants and shook his fanny at a popular Salt Lake City gay club — but then freaked out when a fan tried to take his picture!

“I’m a big fan of Derek’s, and I always thought or HOPED he was gay,” said club regular Ken Lee. But when Ken approached Derek for a photo, the dancer freaked out. “He couldn’t have been more rude or a bigger diva!" Ken said.

“Derek very well may not be gay,” he added. “But he sure was dressed pretty and threw an impressive hissy fit when I asked for a photo!”

Well-dressed and petty? He's two snaps away from a Pride Parade, girlfriend!
