Prince has asked Amy Winehouse to duet with him.
The 'Rehab' singer was said to be "delighted" after the pop legend invited her to fly to his Minnesota home to work on the musical collaboration after Christmas.
A source said: "He is a big fan of Amy and enjoyed performing with her in London recently, he was eager for them to work together sooner rather than later. So he just gave her a call and invited her out to the US.
"Of course, Amy was delighted and jumped at the chance to work with him. You don't turn down Prince."
Prince has reportedly made it clear Amy's visit will be purely a business trip and has suggested her husband Blake Fielder-Civil shouldn't join them.
Last month, Amy made a surprise appearance at the after-show party for the final night of Prince's 21-date residency at London's O2 arena.
The pair thrilled the crowd when they took to the stage for a performance of Amy's track 'Love Is A Losing Game'.
In May, the 49-year-old superstar stated he was a "big fan" of Amy, prompting her to gush: "I'm honoured. I'm a massive fan. I'd love to work with him." |
