Amy Winehouse's ex-husband Blake Fielder-Civil's mother says that she is worried of what he will do when he hears about her death.

Blake Fielder-Civil is currently in prison, serving 32 months for burglary and possession of an imitation fire-arm. He and Amy divorced in 2009, breaking their 2 year marriage. His mother Georgette Fielder-Civil is worried that Blake will harm himself when he hears about the singer's death.

Amy Winehouse was found dead in her apartment after an overdose of drugs and alcohol. 

I can't believe it. I could cry, she told the Daily Star Sunday.

Blake will kill himself. He won't make it without her. He will be devastated, totally and utterly devastated. He'll go straight back to self-harming. I'll have to ring the prison and he'll have to be put on watch. He was always ringing her and she was always ringing him. Blake always wanted her back. She couldn't walk away from him and he couldn't walk away from her. Her and Blake were both lost and we handled it badly. 

The Rehab singer's addiction and struggle with substance abuse were well known, although the cause of her death is not established yet, her post-mortem is supposed to be conducted on Monday, July 25.

Her funeral was earlier supposed to be held on Sunday in accordance with Jewish traditions, but a statement from London's Metropolitan Police ruled this out.

The statement said: Death of Amy Winehouse - a date and time for the post-mortem will not be scheduled before Monday morning, an entertainment.stv report said.
