Charlize Theron puckered up to kiss a woman on Thursday night and raised $140,000 in the process.

The actress, who romanced Christina Ricci in Monster, helped take over hosting duties at the OneXOne charity event in San Francisco, California after Matt Damon pulled out at the last minute - and she made the evening's auction a memorable one for one female fan.

Offering up a 2010 trip to her native South Africa that included World Cup soccer tickets and a meet-and-greet with Nelson Mandela, Theron was frustrated when bidding stalled at $37,000 - far below what actor Jeremy Piven had just raised.

She growled, "For f**k's sake! You can do better. There is no way I am leaving here with Jeremy Piven getting a higher bid."

She then upped the stakes and threw in a seven-second kiss, which sparked a bidding frenzy.

But it was an unnamed woman who landed the prize, bidding $140,000 and locking lips with the Oscar winner for 20 seconds.

Damon was forced to pull out of the charity fundraiser at the last minute due to a family emergency.
