Gene Simmons -- Butt of the Joke

Shannon Tweed better keep an eye on her man, because Gene Simmons has a wandering eye -- toward flamboyant, tall, built men.

TMZ was at Beacher's Madhouse this past weekend at the Hard Rock in Las Vegas, where the KISS bassist was a special guest. Looking completely uncomfortable, Simmons was pulled onstage by a practically naked Leonid the Magnificent (remember him from "America's Got Talent"?) and the awkward ass-grabbing began.

Enjoy! Gene sure didn't.
