Amy Winehouse has abandoned recording the theme to the latest James Bond film because the singer is not ready to work, her producer said Friday.

Mark Ronson, who produced much of Winehouse's Grammy-winning "Back to Black," said the soul diva is "not ready to record any music."

Ronson said the two started work on the track for the upcoming Bond movie "Quantum of Solace" but it would take "some miracle of science" to finish it, he said in an interview with Sky News.

Winehouse's troubles with drugs, law enforcement and her rocky romance with her jailed husband Blake Fielder-Civil have kept the singer in the spotlight.

Police gave her a formal warning last week after she scuffled with two men during a raucous night out.
