Amy Winehouse turned down a duet with Robbie Williams.

The 'Rehab' singer's father Mitch has revealed his daughter was approached by the 'Angels' singer to duet with him, but she told Robbie she thought his idea was a "f***ing" joke.

Speaking on his online show 'Mitch Winehouse's Showbiz Rant', he said: "I'm a bit worried about Robbie, next thing he'll be wanting to make a record with Amy. That's preposterous."

The 58-year-old taxi driver added: "Actually he said that once... he wanted to do a record with Amy. Amy said, 'Are you f***ing joking.' "

Amy is currently working on her long-awaited third album which she has recorded in London and Jamaica.

Mitch recently spoke about his concerns for his daughter now she has seemingly reconciled with her ex-husband Blake Fielder-Civil.

He said: "I'd be devastated, I'm worried about the situation and I'm going to discourage her in every way I can. Their relationship was a disaster, it was destructive and they're lucky that one of them didn't die. Two addicts can't be in a relationship."
