The American singer, who is going out with comedian and Hammers fan Russell Brand, modelled the outfit made of West Ham shirts at the 5 November ceremony.

Designer Siobhan Dillon's creation was seen by millions of viewers around the world and is now on sale at the club.

An initial limited edition run of 50 will be made, priced at £300 each.

Size and payment must be confirmed in advance, and any orders placed by 20 November are guaranteed to be delivered in time for Christmas. Anyone wanting to order one for Valentine's Day must get their order in by Christmas.
