Charlize Theron was not about to be outdone by the likes of Jeremy Piven last night at a charity auction gala for OneXOne. She was originally offering up a trip to South Africa that included World Cup tickets, a safari and a meet-and-greet with Nelson Mandela. When bidding stalled out at about $37,000, she upped the stakes.

"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."

Piven's auction went for $280,000! So, she threw herself in the pot, offering a 7-second kiss for $130,000 to a male bidder:

"Swine flu is going around. This is high risk kissing!" she told him

.

But it was a woman who ended up winning the coveted kiss!

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.

"My boyfriend is not here tonight," she joked during the auction.

It's like a kissing booth - Hollywood style! What a great thing to do for a great cause! I bet Matt Damon was pretty excited at all of the money raised! And maybe a little sad that he missed the event! He had to back out of his hosting duties at the last minute, citing a family emergency.
