Superstar Prince has invited English singer Amy Winehouse to join him on stage in London this summer. The Gett Off hitmaker will perform 21 gigs in the British capital at the new O2 Arena in August (07), with all tickets costing GBP31.21 - a reference to his latest album title 3121. Prince enthuses, "I love Amy's track Love Is A Losing Game. We play that a lot. I'm a big fan. We're still sorting out the support acts but if I saw her onstage I would absolutely ask her to join me." Winehouse responds, "I'm honoured. I'm a massive fan. I'd love to work with him."
