Mark Ronson pulls plug on Amy Winehouse Bond duet

Mark Ronson has revealed he pulled the plug on studio sessions to record the new Bond theme with Amy Winehouse---because she is such a wreck.

And the decision to scrap the project has caused a massive rift between the music-making pals.

Mark said, "We did work on it but we never finished it. I don’t think it will happen unless by some miracle it gets recorded and someone sings on it. I’m not sure Amy is ready to work on music yet."

The pair started work on the track at Mark's studio in Oxfordshire last month, but their sessions soon deteriorated.

Amy is also said to be upset that Mark has spoken publicly about their problems.

And pals fear the rift between her an Mark -- who is a key figure in her career -- will have long-term consequences for the troubled 24-year-old.

One told The Sun newspaper: "Mark has always had a really good influence on Amy. He brought out the best in her and cared for her on a personal level.

"On a professional level he seems to be the only person who can get her into the studio. Without him encouraging her we’re worried."

Amy’s spokesman said: "Mark presented a track to Amy, but she had other ideas about the direction it should take. We’re sure they will continue to make great music together."
