confessed to cheating on Blake Fielder-Civil in divorce papers.
Blake was granted a decree nisi - a preliminary stage of divorce which will then become absolute in six weeks - during a 75-second hearing in the Family Division of London's High Court on the grounds of Amy's infidelity
Neither Blake, 27, nor Amy, 25, attended the hearing.
Court papers show that when Amy was asked if she admitted "the adultery
alleged in the petition", she replied, "Yes."
Blake - who married Amy in May 2007 - filed for divorce from inside prison earlier this year while he was serving a 27-month sentence for perverting the course of justice and grievous bodily harm.
In a question-and-answer session detailed in legal documents submitted to the court, Blake insisted he finds living with Amy "intolerable".
The papers reveal the one-time video production assistant was asked by his lawyer to "state briefly your reasons for saying that the respondent has committed the adultery alleged", to which Blake answered: "The respondent confessed the adultery to me in April 2008."
According to the documents, the couple have lived apart since that date - although Blake was remanded in custody six months after they tied the knot in 2007.
Amy and Blake first met in 2005 and had a turbulent on/off relationship, which inspired the pained lyrics on her worldwide hit album 'Back to Black'.
was plagued by drink and drug fuelled bust-ups and Amy's father Mitch stated on several occasions that he wanted his daughter to walk away from the "self-destructive" romance.
Amy is due in court next Thursday (23.07.09) to face an assault charge.
