The lucky fan from Britain, known only by the name Bossnour, beat 170 other bidders for two tickets to the premiere of the film He’s Just Not That Into You, opening in July. The fan may meet the actress in Los Angeles or New York.
All of the profits from the eBay auction will be given to the charity organisation Oxfam.
In addition to meeting Johansson, the winner will get to have a hair and makeup session, before being taken to the premiere in a limousine.
