The duet was recorded in St Lucia where Winehouse was working with producer Salaam Remi, who has also worked with Green.

A source told the Daily Star that the singer’s voice was “as good as ever” and that her new album was “entirely finished”.

Winehouse’s much-anticipated third album will mark the follow-up to 2006’s ‘Back To Black’. It has yet to be given a confirmed release date.

The singer recently played a series of five gigs in Brazil, for which she was apparently paid £5million.
