Usher Wants Amy Winehouse Duet

And Usher is keen to step into the studio with Amy Winehouse, insisting she's the "only" artist in the U.K. he'd like to record with.

He tells Britain's Daily Mirror, "I would love to work with Amy. I hear she's back and I want us to shock people. She's the only one in the U.K. I want to work with. Her voice is wow, amazing, and she could take music somewhere I've never been before."
