London, July 16 - Troubled British singer Amy Winehouse's marriage will end in a 'quick divorce' Thursday.

Thesun.co.uk reports that Winehouse's drug-ravaged husband Blake Fielder-Civil is asking for the divorce. The 27-year-old Fielder-Civil is claiming her adultery is the reason for the divorce. He may also seek a share in her estimated $17 million fortune.

During their 26-month marriage, the two plunged into heroin addiction that almost destroyed them both, although 25-year-old Winehouse saw her pop career soar.

Fielder-Civil, a video production assistant, was alleged to have fathered another woman's child while in rehabilitation centre earlier this year.
