Singer Amy Winehouse was divorced by her estranged husband today on the grounds of her adultery.

Blake Fielder-Civil, who said the star confessed to him in April last year, was granted a "quickie" divorce from the 25-year-old star at a brief hearing in London.

Fielder-Civil, 27, who described himself as a music video producer, stated in divorce papers before the court he found it "intolerable" to live with Winehouse.

Neither party was present for the proceedings - lasting a matter of seconds - before District Judge Michael Segal at the High Court's family division.

The couple were married in May 2007 in Miami, Florida.

Winehouse admitted the adultery with an unknown person in divorce papers made public today.

Fielder-Civil was granted an undefended decree nisi from the singer.

In a question and answer style document, he was asked: "State briefly your reasons for saying that the respondent has committed the adultery alleged".

He answered: "The respondent confessed the adultery to me in April 2008."

He said that since April 2008 he and Winehouse had not lived in the same household.

Fielder-Civil, whose address was given as Barnby Lane, Claypole, Newark, was also asked: "Do you find it intolerable to live with the respondent?"

He answered: "Yes."

The name of the person with whom the singer is alleged to have committed adultery was stated as "not known".

In a separate document Winehouse was asked: "Do you admit the adultery alleged in the petition?"

The star answered: "Yes."

She also stated that she did not object to paying the cost of the proceedings.

Winehouse said she received the divorce petition in April this year while in St Lucia.
