Scarlett Johansson extends invite to 'Iron Man 2' premiere

(People.com) -- Next spring's "Iron Man 2" premiere will be memorable not only for the stars of the film, but also for two lucky fans -- thanks to cast member and Oxfam Ambassador Scarlett Johansson.

Johansson is auctioning off for charity two movie premiere tickets, as well as a meet-and-greet with the Golden Globe nominee herself.

The auction begins Thursday at 10 p.m. EST at eBay.com/Oxfam and will run through September 24.

All of the proceeds will benefit Oxfam America, an organization long dedicated to finding lasting solutions to poverty, hunger, and social injustice around the world.

"I'm so thrilled to be a part of this eBay charity opportunity, again raising funds for Oxfam," Johansson, 24, said in a statement. "Oxfam is an incredibly worthy organization that I'm most passionate about."

The winning bidder and his or her guest will attend the Los Angeles, California premiere and receive a complimentary session at the Cristophe Salon in Beverly Hills, California to prepare for the red carpet.

Also up for bids: Signed LPs of Johansson's latest single "Realtor" (a duet with Pete Yorn) and the actress's own chair from the set of her hit movie "He's Just Not That Into You."

This is the second year eBay.com and Oxfam America have partnered to offer Hollywood-style experiences featuring Oxfam Ambassadors, including Johansson, Giada De Laurentiis and Colin Firth.

A new celebrity package will debut on eBay every week until Oct. 8.
