Colin Firth is sexy, dashing, Academy award-winning … and available?

Firth, 51, is teaming with Oxfam America, a charity dedicated to ending poverty, to raise funds by auctioning himself. The winning bidder and a friend will meet the King's Speech star at the Dec. 6 premiere of his movie Tinker, Tailor, Soldier, Spy and be chauffeured to a Chateau Marmont after party.

Note to the winner: don't worry if you geek out meeting the Brit face-to-face. Firth has experienced some awestruck moments of his own meeting his idols.

"Ever so often, I will meet someone who I greatly admire and get truly dumbstruck," Firth tells PEOPLE. "I'm a big fan of the people in the world of music and literature. If I'm a big fan of somebody, I prefer to keep at a safe distance because I don't know what I will do."
