Bachelor auctions have been popular gimmicks for raising money, but how often does a celebrated actress get involved? On eBay there is a bid to win a date with Scarlett Johansson, the curvy star of films like "Lost in Translation," "The Island" and the recent period piece "The Other Boleyn Girl."

Like many in Hollywood, Johansson has her pet causes and proceeds from the date will go to Oxfam America, an international development and emergency relief agency.

The winner will receive two tickets to the world premiere of the film "He's Just Not That Into You," starring Johansson, Drew Barrymore and Ben Affleck, chauffeured car service to the premiere, hair and makeup for one by Prive and a chance to meet Johansson at the premiere. The location has not been determined yet but will be in either Los Angeles or New York this July.

Airfare and the hotel, however, are not included. Bidding is up to $300 as of this writing. The auction will last until March 12th, so save your pennies.
