Liam Gallagher and Nicole Appleton will reportedly file for a “quickie divorce” on Tuesday.
The couple started dating in 2000 and got married in 2008, before splitting up in 2013.
According to UK newspaper The Mirror, documents filed at London’s High Court show the couple’s case is the second in a list of 12 hearings set to start at 10am on Tuesday.
Liam and Nicole have one child together - son Gene, 12. The marriage broke down in July of last year after reports surfaced that Liam had fathered a daughter with American journalist Liza Ghorbani.
Liam allegedly broke the news to Nicole over the phone while she was on holiday with her older sisters Lori, Lee and Natalie in Florida, and he was performing in Ibiza.
The former Oasis star has apparently moved in with new girlfriend Debbie Gwyther, the manager of his fledgling band Beady Eye.
Nicole posted a series of inspirational tweets at the end of 2013, talking about what she learned from the year.
“No matter how good you treat people there will always be people that are blind, take advantage of it and regret it when it’s gone,” she wrote. “You’re gonna get talked about, left out, used, and even lied to but you have to decide who’s worth the pain and who isn’t. Even the people you care about the most can walk out of your life. 2013 taught me to be prepared for whatever life throws at you.”
