Mark Ronson has claimed he had no knowledge of Amy Winehouse's Twitter outburst about him.

On Saturday (September 18), the singer, who worked with Ronson on her second album ‘Back To Black’, accused the producer of taking too much credit for the record.

She wrote on 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.”

But Ronson has said he wasn't aware of the attack. "I don't know anything about it,” he told The Sun.

Winehouse and Ronson most recently recorded a song for a new Quincy Jones-curated covers album, which is due out later this year.

The producer was also thought to be working with the star on her new album, which Winehouse has said will be released no later than January next year.
