Charlize Theron’s got a number of titles: Oscar winner, red-carpet diva, and now, official Hollywood butt-kisser. Indeed, the Monster star, admittedly having popped a painkiller for a neck spasm, pressed her lips to fellow honoree Shirley MacLaine’s backside at Tuesday’s 12th annual Premiere Women in Hollywood gala, according to a report in USA Today. ”I’m going to kiss your a– too, but literally,” Theron announced before doing the deed. ”That’s the best I’ve had in 10 years!” replied MacLaine. Sadly, no one was feeling loopy enough to shout ”Glaaadiator!”
