Chris Martin plays for Madonna

Chris Martin played a song for Madonna with his wife Gwyneth Paltrow at a recent party in the English countryside, according to reports.

The Coldplay singer and American movie star were invited to a party hosted by the Queen Of Pop at her home at Ashcombe Manor, in Tollard Royal on the Wiltshire-Dorset border.

Madonna has revealed in an interview with Vogue magazine that all the guests were asked to contribute a song, poem or piece of acting, leading to Martin and Paltrow's song.

Apparently they were joined by Paul McCartney's daughter Stella in a rendition of "American Wife", a reworking of Madonna's "American Life".

Madonna said the party was to mark her fourth wedding anniversary. She explained: "Gwyneth did a fantastic rap and Stella sang background vocals and, well, Chris played the piano."

Elsewhere at the showbiz knees-up, Sting reportedly played a lute, while Madonna herself performed a scene from the play "The Town Wench Or Chastity Rewarded".document.write(unescape("
