Singer will take to the stage as part of the rapper's super group

Jay-Z has persuaded Amy Winehouse to join him on stage at Glastonbury.

And the US rapper, 38, has also roped in wife Beyoncé Knowles, 27, Coldplay frontman Chris Martin, 31, and Rolling Stones guitarist Keith Richards, 64.

Amy, 24, is expected to perform her own set on Saturday too.

‘Jay-Z wants an amazing headline show and has gone through his address book to ask famous friends to join him,’ a source tells the Daily Mirror.

‘He thinks Amy is amazing and thought it would be the perfect chance to work with her.’

Meanwhile, Amy’s manager has confirmed she will play at Nelson Mandela’s 90th birthday concert in Hyde Park tonight.
