An autographed jockstrap worn by British pop star Robbie Williams in the music video for his track Sing When You're Winning is going up for sale online.

The singer wore the white undergarment as part of a soccer kit in the 2000 promo, and now it is expected to draw bids of between $600 (£375) and $800 (£500) when the item hits the auction block at Australia's LeonardJoel.com on 5 June (14).

The lot, which had previously been sold in 2001 and 2006, will be part of the Beatles & Entertainment Memorabilia Auction, which features a selection of photographs from the Fab Four's tour Down Under and autographed concert posters from Michael Jackson and Coldplay, among the other highlights.
