Stevie Wonder wanted Amy Winehouse duet
Stevie Wonder had been planning to duet with the late soul singer Amy Winehouse before her death in July 2011.
Stevie Wonder had planned an "amazing" duet with Amy Winehouse.
The 'Superstition' hitmaker - who was friends with late stars Michael Jackson and Whitney Houston - wanted to work with the British singer but she passed away before they had chance.
He said: "It's been a heartbreak. Obviously I knew Michael. I knew Whitney too and I understand Amy came to my concert in England a couple of years ago.
"I was thinking about us doing a duet - an old Marvin and Mary Wells song called 'Once Upon A Time'. It would have been amazing."
The 63-year-old singer also doesn't enjoy having his music categorized because he thinks labels are "bulls**t".
He said: "I've never said I was a soul artist or an R&B artist. They're just labels.
"When you're soul it means black and when you're pop it means white. That's bulls**t. If it's good, it's good.
"It's like that old Jerry Reed song, 'When you're hot, you're hot, when you're not, you're not.' "
