Nelson Mandela invites Amy Winehouse to sing at his birthday bash

An insider tells Mirror: "Amy was stunned when she got the call. She thought it was a hoax - well you would wouldn't you!

"But once she worked out it really was him she accepted straight away and gushed about how much she was looking forward to it. She couldn't believe it."

Five-time Grammy-winner Amy, 24, will headline the concert to mark Nelson's 90th birthday in London's Hyde Park.

The bill boasts a host of big names, including Sir Elton John, Razorlight, Queen, Bono, and Annie Lennox. And special guest Dame Shirley Bassey has been asked to lead a rendition of Happy Birthday.
