Ronson refuses more work with Winehouse

Mark Ronson has been telling friends that his working relationship with Amy Winehouse is officially over for good after she failed to show up to a video shoot with him.

The New York DJ produced Winehouse's hit album Back to Black and was due to film their new single together on Friday.

But he was left fuming when she bailed out on him and was photographed holidaying in St Lucia with her husband, Blake Fielder-Civil, the following day.

A source told the Daily Mirror: "After all the hassle that Amy created by pulling out of the video shoot, seeing pictures of her living it up infuriated Mark - and justifiably so.

"He has been hugely concerned about Amy and considers her a great friend. But he's telling friends their working relationship is over for good."
