The All Saints singer's legal separation to the former Oasis singer was completed within 68 seconds of the judge assessing the case at the Principal Registry of the High Court in London on Tuesday (08.04.14).
The end of their marriage comes after it was revealed last July that Liam - who has 12-year-old son Gene with Nicole - had fathered a child with American journalist Liza Ghorbani during an affair.
According to court papers Nicole said Liam ''admitted adultery to me prior to it becoming publicised in national newspapers'' and she found it ''intolerable'' to live with him afterward.
The 41-year-old musician confessed to cheating in the legal paperwork, answering ''yes'' when he was questioned on the topic and he agreed to pay Nicole, 39, ''reasonable costs''.
Liam is now living with Beady Eye's ex-manager Debbie Gwyther after moving out of the home they shared together.
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.
