Charlize Theron Kisses Woman For $140,000 (VIDEO)

Charlize Theron made out with a female stranger - for charity.

Theron was part of a live auction at a party for OneXOne in San Francisco Thursday night. When bidding stalled on a South Africa/World Cup package she was auctioning, she upped the pot by offering some personal lip service.

Us Weekly reports:

...bidding stalled at $37,000, far below the $280,000 Jeremy Piven had just raised.

"For f*** sake! You can do better," she tells attendees. "There is no way I am leaving here with Jeremy Piven getting a higher bid. I've got t**** for God's sake."

To sweeten the pot, she offered up a 7-second kiss for $130,000 to a male bidder. "Swine flu is going around. This is high risk kissing!" she told him.

After one man bid $135,000, a woman upped the stakes to $140,000 -- ascending the stage for a 20-second smooch as the audience counted down.
