Ooo-er, remind us never to get on the wrong side of Amy Winehouse.
The star has taken to Twitter to rant against (now ex) friend and producer, Mark Ronson after he claimed that he “created the tracks” for her hit album, Back to Black.
The star tweeted: “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)”

Oh dear, shame that had to happen because we really liked what Mark and Amy did with Valerie....
What do you think? Will Mark and Amy kiss and make up soon? Tell us on Twitter @areyouentwise and on our Facebook fan page.
Lets hope Amy doesn't go back to these....
