The pair have ended their six-year marriage
The All Saints singer, 39, was granted a decree nisi at London’s Principal Registry Of The High Court and a decree absolute is expected in six weeks.
It was heard in court that Nicole had found it ‘unbearable’ to live with Liam, 41, after he admitted to cheating with journalist Liza Ghorbani last July.
Liam had told Nicole that he’d been unfaithful before the news broke and she was pictured without her wedding ring a few days later.
It was alleged at the time that Oasis rocker Liam had secretly fathered Liza‘s baby daughter Gemma, who was born in early 2013.
Neither Liam nor Nicole – who wed in 2008 and have son Gene, 12, together – attended the hearing yesterday but Nicole confirmed Liam‘s infidelity in a statement.
‘The respondent admitted adultery to me prior to it becoming publicised in national newspapers,’ said Nicole.
‘The woman with whom the respondent committed adultery now has a child by the respondent.’
