AMY WINEHOUSE's father MITCH will force her husband Blake Fielder-Civil to enter rehab when he is released from prison - in a bid to save his daughter from a life of drugs.

Fielder-Civil is currently awaiting sentence in London's Pentonville Prison after pleading guilty to perverting the course of justice and causing grievous bodily harm (GBH) in relation to an attack on pub landlord James King in June 2006.

The 25-year-old could walk free as early as 21 July (08) following his sentencing.

And Mitch is determined to make sure that Fielder-Civil is drug-free after his time behind bars, because he wants to make sure his singer daughter isn't tempted back to a life of wild partying.

He says, "If he comes out, they can't carry on as they have. I don't think he's been clean in prison. He's a fit young man - he could carry on the rest of his life like that - but Amy can't. If he comes out he will go straight into rehab."
