Producer Mark Ronson says he and Amy Winehouse have abandoned recording the theme to the latest James Bond film because the singer is not ready to work, according to AP reports.

Ronson says the singer is "not ready to record any music." He produced much of Winehouse's Grammy-winning "Back to Black." He made the comments in an interview with Sky News on Friday.

Ronson says 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.

Winehouse's troubles with drugs, the police 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.
