Washington, Oct 24 Charlize Theron auctioned off a kiss to a woman for the price of 140,000 dollars.

The South African-born actress took part in a live auction during a gala for the charity OneXOne in San Francisco, reports Usmagazine.com.

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.

However, she raised the stakes after bidding stalled at 37,000 dollars, far less than the 280,000 dollars Jeremy Piven had just raised.

She told attendees: "For f*** sake! You can do better. 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 deal, she offered up a seven-second kiss for 130,000 dollars to a male bidder, but a woman in the audience quickly bettered the deal with a 140,000 dollars bid.

The 34-year-old actress is in a long-term relationship with actor Stuart Townsend, 36.

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