London, May 18 : Amy Winehouse's mum has blamed the troubled singer's hubby, Blake Fielder-Civil, for her "downfall".
Janis Winehouse said that her daughter had only begun to take hard drugs and harm herself after she met Fielder-Civil.
But Fielder-Civil's own mother Georgette accused Winehouse's parents of failing to control her daughter's descent into a drug-fuelled haze.
In a bitter newspaper interview Janis, 53, said: "As far as I'm concerned, Blake more than played his part in Amy's downfall."
"People I trust have told me that Amy didn't start on the hard drugs until she met Blake - and I think that says it all," the Telegraph quoted her, as adding. "Don't get me wrong: I know she dabbled in drugs before. I was aware of her smoking dope in her teens. But she was always adamant that she would never touch the hard stuff, that she didn't need it. That all changed when she met Blake.
"She didn't start self-harming until Blake came along, either.
"I know Georgette, Blake's mother, says the opposite and blames Amy for Blake's downfall. But that's absolute rubbish."
Janis, who is divorced from Amy's father Mitch, said she was "devastated" by seeing pictures of her daughter smoking crack cocaine, but said it was not too late for the singer to turn her life around.
"I don't think she's totally lost control. She's a girl who lives on the edge; she toys with it," she said.
"But she has an awareness of it, too - and that will save her in the end. Maybe it's just because I'm her mother, but I think Amy will have a resurrection, and everyone will say: I thought she was going to kill herself - but here she is," she added.
