Charlize Theron's $140,000 Lesbian Kiss for Charity!

Oscar winner Charlize Theron took one for the team mixing philanthropy with French kissing at a charity event to the tune of $140 K in San Francisco Thursday.

Theron was on hand to help raise money for the charity OneXOne, which delivers food and water to children around the globe.

Bids for a trip to South Africa to meet Nelson Mandela fell flat at $37,000. That's when South Africa native Theron made an offer that could not be refused; to make out with the top bidder!

"For fuck's sake! You can do better," Theron taunted. "There is no way I am leaving here with Jeremy Piven getting a higher bid. I've got tits, for God's sake."

Piven's prize sold for $280,000, and not to be outdone by the Entourage star, Theron threw in the makeout session, which pushed the bids into six digits.

Theron, an ardent supporter of LGBT rights, didn't bat an eyelash when a woman out bid the previous top bidder, a man, by $5,000 and upped the bid to $140,000.

"My boyfriend isn't here tonight," Theron teased as the woman made her way to the stage to collect her prize.

The girl-on-girl kiss for charity lasted more than 20 seconds, according to Hollyscoop. And the lucky lady even picked Theron up off the ground for a second. Of course, Theron is no stranger to kissing the ladies, having indulged in some heavy smooching with Christina Ricci in Monster and Penelope Cruz in Head in the Clouds.
