Christina Aguilera and Cher are offering up signed BURLESQUE memorabilia for an auction in aid of a hunger relief charity.
The two singing superstars team up for the new movie and they've both autographed two limited edition promotional posters to be sold off to benefit the United Nations World Food Programme (WFP).
Aguilera has also handed over a signed a copy of her Bionic album, a vinyl edition of the record, two collectible photographs and a custom designed box.
All profits from the eBay.com auction, which ends on 29 November (10), will be handed to the WFP.
