One lucky woman was able to get a 20-second kiss from the Oscar winning actress after winning a bid of $140,000.

Charlize Theron participated in a OneXOne Charity event on Thursday night in San Francisco and auctioned off a two-week trip to South Africa. The trip includes tickets to watch the World Cup in summer 2010, a safari and a chance to meet Nelson Mandela.

The 34-year old actress offered a 7-second kiss to a male bidder for $130,000. “Swine flu is going around. This is high risk kissing!” she told him.

After a little while, a woman raised the bid to $140,000 and won. Theron had to kiss the winner for 20 seconds.

Aside from Theron, Jeremy Piven also took part at the said event and was able to raise $280,000 for a walk-on role on the hit HBO show, “Entourage”.

Other celebrities who joined the event were Josh Groban, Carlos Santana, Laila Ali, and David Arquette.
