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-documented 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 pair were granted a divorce at a brief hearing at the High Court in London, which neither party attended. Their case was listed as Fielder-Civil B v Winehouse A J, among 25 divorce cases.

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.

Winehouse's spokesman confirmed the divorce, but made no further comment.

Her parents said in a television interview last month that their daughter was "in denial" about her addiction but had been recovering over the past few months while on the Caribbean island of Saint Lucia.

"For the last six months there's been a remarkable recovery," said her father, Mitch Winehouse, saying she was on a drug replacement programme although still drinking heavily.

"A gradual recovery, which is good. With slight backward steps — not drug backward steps, more drink backward steps if you follow my drift. I think that will be the pattern of recovery."

He has in the past blamed Fielder-Civil for fuelling his daughter's habit, and said: "The option of them being together is too horrible to contemplate."
