Mark Ronson has developed an unfortunate habit of putting his foot in it (you'd almost think he had a new album to promote). First, there was his comment, in an interview with Esquire, that he regretted dating a certain 'It' girl: "I look back on it," he lamented, "and think, 'God, did I really just step into the cliché like that?'" Said cliché was, gossips presumed, his relationship with model Daisy Lowe, whom he ran into at the GQ Men of the Year awards, to which she was accompanied by her new boyfriend, Doctor Who. Then, on Friday night, Ronson told Jools Holland that as a producer, he had taken Amy Winehouse's demos and from them "created" the hits on her album Back to Black. "[R]onson you're dead to me", Winehouse tweeted in response, "one album I write an [sic] you take half the credit – make a career out of it? don't think so BRUV". The lingo is authentic, though Ms Winehouse's account remains unverified by Twitter HQ (so may not, in fact, really be hers). It's also possible she was joking.
