In a 1980's pop gossip dream moment, former teen queen Tiffany outed New Kids on the Block member Jonathan Knight as gay during an interview with Debbie Gibson.

Tiffany, whose mall performances of I Think We're Alone Now and Could've Been shot her to stardom, told millions of TV viewers that her ex-boyfriend Jonathan Knight of New Kids on the Block is gay.

During an interview with Andy Cohen on Bravo's Watch What Happens: Live -- where Tiffany was a guest alongside fellow former teen queen Debbie Gibson to promote their upcoming SyFy flick Mega Python vs. Gatoroid -- the singer admitted that she dated Jon and found out later he was gay.

"The quiet one, the shy one," Tiffany admitted. "[Jonathan Knight] became gay later. I didn't do it. I had issues with that. I was thinking maybe I did. Now looking back when we were dating, he was so much fun. We used to do facials together. He was so easy to talk to."

While rumors of Jonathan's sexuality have abounded for years, and photos of a man said to be his longtime partner surfaced online during one of NKOTB's recent tours, the singer has never publicly addressed the subject.

Tiffany's unauthorized outing doesn't seem to have changed that policy: He still has no comment.
