LONDON, ENGLAND - Troubled British singer Amy Winehouse was divorced from her estranged husband, Blake Fielder-Civil, in London on Thursday after two years of marriage, her spokesman said.

The 25-year-old won five Grammy awards off the back of her debut album "Back to Black" and the hit single "Rehab," but has since been engaged in a well-publicised struggle with drugs.

Fielder-Civil's spokesman said in January that the 27-year-old had begun divorce proceedings against Winehouse "on the grounds of Amy's adultery."

The couple married in Miami in May 2007 but have had a tempestuous relationship, while Fielder-Civil spent much of last year behind bars for a vicious attack on a pub landlord and a subsequent attempt to cover it up.

Neither party was present for the divorce proceedings on Thursday. Winehouse's spokesman confirmed the divorce, but made no further comment.
