Adam Lambert Kissed A Girl And He Liked It!

Openly gay American Idol runner-up Adam Lambert admitted that he kissed Tik Tok singer Ke$ha -- and he liked it!

"She's really pretty and we were laughing and we just started kissing," he told WBLI's BLI In the Morning. "It was pretty innocent to be honest with you. I mean, it wasn't too dirty." Surprising for a girl who sings that she brushes her teeth "with a bottle of Jack!"

Adam officially came out on the cover of Rolling Stone magazine last year, but says he has no problemo kissing a girl, as long as she's got good "energy"!

And we're betting the 22-year-old is bubbling over with it!
