New Kids on the Block singer Jonathan Knight has announced – and according to him, it's not news – that he's gay.

Last week the pop singer laughed off being outed by nineties pop star Tiffany.

Talking on bi – not gay – cabler Bravo's late night chat show Watch What Happens Live, Tiffany told her host Andy Cohen that Knight was gay.

Afterward, she apologized for the gaffe, saying on Twitter, “Really didn't know that was the wrong thing to say. Never meant to hurt Jon.”

Apparently, it wasn't the wrong thing to say, because Knight was under the impression that everyone knew he was gay.

In a blog post titled TO ALL MY FANS WHO HAVE EXPRESSED CONCERN, Knight, 42, addressed the issue of his sexuality. (The full blog post is available at Towleroad.com.)

“I have never been outed by anyone but myself! I did so almost twenty years ago. I never knew that I would have to do it all over again publicly just because I reunited with NKOTB! I have lived my life very openly and have never hidden the fact that I am gay!”

“I love living my life being open and honest, but at this time I choose not to discuss my private life any further! My fellow band members don't discuss their private lives and their loved ones and I don't feel that just because I am gay, I should have to discuss mine!”
