Nicole Appleton ends marriage to Oasis' Liam Gallagher
The couple were not at the Principal Registry of the High Court's Family Division for the hearing.
The All Saints singer and the Oasis star were the second in a "quickie divorces" list of 12 who were granted a decree nisi by District Judge Anne Aitken.
The pair, who have a 12-year-old son, married on St Valentine's Day in 2008.
Among the documents made public yesterday was a sworn statement signed by Appleton last December in which she said that Gallagher "admitted adultery to me prior to it becoming publicised in national newspapers", adding that the woman with whom Gallagher committed adultery "now has a child" by him.
She said that she first knew about the adultery on July 17, 2013, and had not lived with Gallagher since, as she found it "intolerable".
In papers acknowledging the proceedings, Gallagher replied "yes" when asked if he admitted the alleged adultery and said he did not intend to defend the case.
The marriage foundered after reports that Gallagher (41) had fathered a daughter with a US journalist.
In the decree nisi document, the judge held that Ms Appleton had "sufficiently proved" the contents of her petition and "is entitled to a decree of divorce".
