No, Charlize Theron hasn't changed professions (unfortunately), the money was used for charity.  More specifically, it was for OneXOne, a celebrity driven charity devoted to helping those in need throughout Africa.  Anyway, the situation went like this:

Theron, 34, took part in a live auction during a gala for the charity OneXOne in San Francisco Thurs. Oct. 22.

And while she was initially selling a 2010 trip to South Africa that included World Cup tickets, a safari and a meet-and-greet with Nelson Mandela, she raised the stakes when 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.

So there you have, an innocent kiss for a LOT of money.  I am most curious about who whe winner is and what she does for a living ...

Anyway, here's the video:
