Mark Ronson has admitted that he is “not sure” whether he is producing Amy Winehouse's next album.

Ronson was behind the singer's last LP, 2006's 'Back To Black', and had been linked to her next studio effort.

But the producer has now cast doubt over whether the pair will be working together again.

“I’m not sure. Whenever I’m producing a record with Amy or whoever, it’s always about the songs, so you have to hear the songs before you decide what you’re going to do,” he told the Metro.

“Obviously there’s a chemistry in the record that we made together. I hope if we did something together again it would be as good.”

Earlier this month, Winehouse hit out at Ronson on Twitter and claimed that he had taken too much credit for 'Back To Black'.

But the star later apologised for her comments, and said: "Ronson I love you.”

In July, Winehouse claimed that her follow-up to 'Back To Black' would be released no later than January next year.
