In court papers, Winehouse was asked: 'Do you admit the adultery alleged in the petition?', and she said: 'Yes'.

No name is given for the person she had an affair with.

Fielder-Civil, who now lives in Nottinghamshire, has also said that he finds it 'intolerable' living with the singer and they have not shared a home since April 2008.

Winehouse, who has an estimated $17 million fortune, has agreed to pay for the cost of the divorce proceedings.
