British pop star Amy Winehouse lashed out at her longtime producer and collaborator Mark Ronson last weekend on her Twitter account. Winehouse accused Ronson of trying to cash in on her fame after Ronson appeared on the British TV show "Later...With Jools Holland" and claimed to have written tracks on her hit album, "Back to Black". The massage read: "Ronson you're dead to me; one album I write and you take half the credit - make a career out of it? Don't think so BRUV".
Winehouse has been working on a new album with producer Salaam Remi and Ronson has reportedly not been involved. Winehouse has said the new album will be ready for release no later than January.
