Amy Winehouse and her husband have flown to a rehab clinic in the US.

Rehab singer Amy and Blake Fielder-Civil agreed to the move after seeing their dads almost coming to blows over their children's cocaine and heroin use.

A source told the Daily Mirror: "It broke Amy's heart to see her parents and in-laws fighting."

The source added: "That was the point when she realised all the drink and drugs were causing huge problems for everybody."

Last Wednesday Amy was taken to a central London hospital after collapsing with a drink and drug overdose which had reportedly seen her take ecstasy, cocaine, heroin, ketamine and alcohol.

Upon release from hospital Amy checked into the Four Seasons Hotel in Hook, Hampshire but is alleged to have been caught smoking heroin with Blake by her best friend Juliette Ashby.

The source said: "They both admitted taking cocaine and heroin. But they denied they had been injecting heroin.

"But now they realise that if they don't get help now, they will both die young. This is their watershed, their wake-up call."
