Amy Winehouse tried to kill herself two months before she died.

The 'Back to Black' hitmaker's ex-husband Blake Fielder-Civil has shockingly revealed she ''slashed herself'' in a bid to commit suicide just eight weeks before she died aged 27 in 2011.

Blake - whose new partner Sarah was going into labour when Amy called him to remind him it was their wedding anniversary - recalled: ''I told her I couldn't talk, as Sarah was having my baby and hung up. In hindsight I should have known that would really upset and hurt her. Amy would have loved to have a child, yet it was Sarah having a baby with me and not her. But I was caught up in the moment and I didn't think.

''The day after, I phoned her to apologise and say happy anniversary and she told me she had cut herself really badly. She said it had been serious. But Amy really no longer cared if she lived or died. She was completely indifferent and there's a very fine line between that and suicide. Amy was a serious danger to herself.''

Amy died of alcohol poisoning but Blake doesn't believe it was an accident.

The former video production assistant is convinced the star - who thought she was pregnant with fiancé Reg Traviss' child when she died - committed suicide and everyone close to her should share part of the blame.

He said: ''I suspect Amy's death was a suicide. After years of drinking she must have known she was drinking far beyond what she could handle. Maybe she expected someone to come in and stop her, take the bottle away. But instead she was left alone to drink herself to death in that house.

''The people around her were so busy celebrating our divorce and her giving up her heroin habit that they didn't see how much work still had to be done. Each and every person close to Amy, including me, deserves a share of blame.''

During their two year marriage which ended in 2009, the 'Rehab' singer and Blake were addicted to heroin and alcohol, though Amy gave up the former when Blake went to prison for assaulting a pub landlord.

However, the 34 year old admitted she couldn't kick the booze and would drink ''miniatures''.

He told The Sun newspaper: ''Amy drank miniatures -- it was her only way of having a semblance of control over the situation. She would have six or seven every day.

''But that way she could tell herself she hadn't had a full bottle. It was like a heroin addict smoking heroin, but saying, 'At least I don't inject it'. After we divorced in 2009 she'd visit me in Sheffield, and she would be sweating and shaking really badly. It was awful to witness.''

Though she tried to kick her habit and sought medical help, in a bid to feel good about herself she decided to get plastic surgery on her breasts instead.

He added: ''It was so obvious she had a drink problem. In November 2009 she went to a clinic in Harley Street to detox but ended up having a breast enlargement instead, which I thought was insane.''
