Amy says `Ronson is dead for me`

London: One time super team - Amy Winehouse and Mark Ronson-have allegedly parted ways and the `Rehab` singer has claimed that the superproducer is "dead" for her.

Apparently the comments stem from Ronson``s interview to musician-turned-TV presenter Jools Holland where he said he created the tracks on ``Back To Black`` from the singer``s demos.

Winehouse accused Ronson of taking credit of her fame for his own blossoming career.

"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," the Daily Star quoted Amy as saying.

Ronson helped Winehouse achieve a worldwide smash with her Grammy-winning 2006 release ``Back to Black``, and the pop star returned the favour by singing Valerie for the DJ``s covers compilation Version.

The pair re-teamed to record a song for a new Quincy Jones tribute record, but their relationship has since soured.
