Amy Winehouse - Fielder-Civil Wants Hush Money Over Winehouse Marriage

The husband of troubled singer AMY WINEHOUSE is demanding a $1.46 million (GBP1 million) pay-off to keep quiet about their marriage.

In November (08) Blake Fielder-Civil reportedly vowed to split from the Back to Black hitmaker to help her win her battle against drug addiction.

But according to a U.K. tabloid, he has now demanded cash from the singer's manager - and threatened to write a tell-all book about his relationship with the star if he isn't paid.

A source tells Britain's News of the World, "He's so two-faced. He just wants a pay-off. Money's his driving force."

Fielder-Civil was released from prison in early November (08) after serving almost a year behind bars in relation to an attack on a pub landlord in 2006.

As part of his early release deal, he agreed to check straight into rehab in Surrey, England, and spend a month undergoing treatment for his drug addiction.

But he has since failed a drug test and faces staying in custody until 2010.
