Nicole Appleton was granted a divorce from Liam Gallagher within 68 seconds of the judge assessing the case.
The All Saints singer has endured a turbulent several months after it was revealed last July that her husband had fathered a child with American journalist Liza Ghorbani during an affair, but there was a swift conclusion to their legal separation which was heard at the Principal Registry of the High Court in London by Judge Anne Aitken.
The case - titled Appleton N M v Gallagher L J P - was the second of 13 undefended cases analysed by the judge and according to court papers Appletone said Gallagher "admitted adultery to me prior to it becoming publicised in national newspapers" and following his confession it became "intolerable" for her to live with him.
Gallagher, 41, confessed to cheating in the legal papers that were filed, answering "yes" when he was quizzed on the topic and he agreed to pay Nicole, 39, "reasonable costs" bringing an end to their six-year marriage and 14-year relationship.
The former Oasis singer - who has 12-year-old son Gene with the blonde beauty - was also revealed to be having an affair with his current band Beady Eye's ex-manager Debbie Gwyther, whom he is now living with.
The Wonderwall singer also has two other children, 16-year-old daughter Molly, who he fathered during a brief fling with singer/songwriter Lisa Moorish, and 14-year-old Lennon, his son with first wife Patsy Kensit.
