Mark Ronson says he doesn't know about Amy Winehouse's Twitter outburst

Mark Ronson has claimed that he has no idea of Amy Winehouse's Twitter outburst, where she slammed him for implying he masterminded every track on Back To Black.

Taking to the decks last night at the MTV Presents gig in Belfast, he even played the hit cover of Zutons track Valerie that Amy provided vocals for.

"I don't know anything about it," the Sun quoted him as saying.

Amy sparked a feud when she slammed the producer last week via Twitter.

"ronson you're dead to me. one album i write an you take half the credit- make a career out of it? don't think so BRUV (sic)," she wrote.
