London, Jan 27 : Amy Winehouse's jailed hubby Blake Fielder-Civil has revealed his biggest nightmare- his wife has been killed by her drugs habit.

Fielder-Civil has warned the junkie singer:"Quit smoking crack or you'll be dead in three months."

"Every day I fear the prison chaplain is going to walk into my cell and break the news that Amy is dead," News of the World quoted him, as saying from the prison.

The 24-year-old Winehouse went into rehab on Jan 24 just days after a shocking video was released of her smoking deadly crack at her seedy flat in Bow, east London, while already high on cocaine, ecstasy and valium.

Blake talking through his devoted mum Georgette, said: "I'm so relieved she has finally taken my advice after I begged her to go into rehab."

"I even threatened her with divorce because I thought it would be the only thing to make her see sense. My parents have both pleaded with me to divorce Amy and I told her so before she finally agreed to go in for treatment.

"They think she's the Black Widow who will be the death of me if I don't end our marriage. But I'd prefer to have a short life with Amy than a long life without her," he added.
