Adam Lambert

Adam Lambert sparked quite the controversy when he kissed a man on stage at the American Music Awards last month, but it turns out that the “American Idol” runner up actually learned how to kiss from a girl.

Fox411 caught up with Lambert Friday Night at Z100’s Jingle Ball at Madison Square Garden where he told us (and some adoring fans) all about how he wasn’t always into boys.

“When I was 14 yes, I had a girlfriend. She was 18 and her name was BJ and she was from Compton. Can you imagine this little red head kid and a big black girl? She taught me how to make out.”

But the “Idol” runner-up also had some words of wisdom for his fans.

“Everyone should get out of the mirror. That’s not what matters. We are programmed in society to be so hard on ourselves and our appearance.”

Still, that doesn’t mean that he is immune to being a victim of his own appearance. Backstage, he refused Wonka candy and opted for Five mint gum instead.

“I’m on such a diet now,” he told Fox411. “I want to stay in great shape so no candy for me.”

But it’s not the fear of packing on the pounds that keeps him up. Instead, he told us it’s “people not wanting to buy my music!”

And despite a tough year, Lambert’s has resigned himself to keeping to his 2010 New Year’s resolution, which will no doubt help him weather the storm of his AMA controversy.

“I want to continue to stay positive and make my music,” he said.
