Amy Winehouse's in-laws have urged fans to stop buying her records. They say a boycott would send a message to the singer and husband Blake Fielder-Civil that they must tackle their drug problems. Fielder-Civil's parents, Giles and Georgette, fear one or possibly both of them will die if they do not sort themselves out.

They said the couple were drug addicts in denial.

Mr and Mrs Fielder-Civil also said the singer should not be given any awards, to show the couple's behaviour was not acceptable.

He believed they were taking crack, and there had been instances of heroin use.

He added: "I think they believe they are recreational users of drugs, and they are in control, but it seems to Georgette and I that this isn't the case."

His wife said: "I think they both need to get medical help, before one of them, if not both of them, eventually will die."

But Winehouse's father, Mitch, said that telling fans to boycott his daughter's albums was "clutching at straws".

He told Radio 5 Live: "There's only one way out of this, and anyone with drug experience will tell you, the only way out is not sectioning them, not locking them up; at some point they are going to reach rock bottom, and at that point they will say, I don't want to do that any more."

Fears continue to grow for Winehouse, who was pictured bloodstained last week following an alleged row with her husband.

Police were called to London's Sanderson Hotel by a worried onlooker, but the singer refused to press charges.

Winehouse was wearing blood-soaked ballet shoes, with bruises to her neck, bandages on her arms and make-up smeared down her face.

Fielder-Civil had livid scratches covering his face and neck.

Winehouse was admitted to hospital earlier this month after a reported overdose of heroin, ecstasy, cocaine, ketamine and alcohol.
