Tiffany and Jonathan KnightRumors have surfaced in the past regarding New Kids on the Block member Jonathan Knight's sexuality, but the pop performer has never admitted to being gay.

However, '80s teen queen Tiffany told millions of TV viewers last Thursday that Knight indeed is gay.

Tiffany appeared on Bravo's 'Watch What Happens: Live,' alongside Debbie Gibson, to discuss their roles in the upcoming Syfy original movie, 'Mega Python vs. Gatoroid,' premiering Jan. 29.

During their sit down, host Andy Cohen asked Tiffany if she had cozied up with any of the NKOTB boys back in her days as a touring mall songstress. Her response: Jonathan Knight.

"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."
