The Sing star has handed over his signed Superman boxer shorts to an auction in aid of breast cancer awareness drive CoppaFeel, which will be held in Woolacombe in England.

Other stars to have contributed underwear to the sale include actress/model Kelly Brook, diving star Tom Daley, and model Cara Delevingne, who has handed over a signed Calvin Klein crop top.

"Even if some of them only sell for a fiver (£5), it wouldn't matter to me," says breast cancer patient Heather Walters, who has organised the auction.

The sale closes on 3 November (15).
