Scarlett Johansson has helped raise thousands at a charity auction - one lucky fan has won the chance to accompany her to a future movie premiere after entering the final bid of $40,100.

The online auction site eBay.com was visited by 695,183 interested parties and received 170 bids for the date.

But the 10-day sale ended on Wednesday - and a U.K-based user named bossnour was slated as the top bidder.

The fortunate fan will accompany the star to the premiere of her forthcoming movie He's Just Not That Into You in Los Angeles in June next year.

All proceeds from the Auction Cause sale will go to charity Oxfam.

The Lost In Translation star isn't the only star who has offered themselves up for auction for Oxfam; George Clooney is also looking for a date to attend the premiere of his new film Leatherheads, while Minnie Driver is auctioning off a $100,000 lunch date as part of an initiative between the actress' hit U.s. TV show The Riches and Oxfam America.
