He has written a book in the round about his celebrity antics.
And one of Lily Allen's most daring revelations is that he had sex with Oasis rocker Liam Gallagher – while he was still married to Nicole Appleton of All Saints.
It is said that the incident occurred on board a flight to Japan, where they both performed at the Fuji Rock Festival in July 2009.
The singer also suggests that they had another attempt in the Asian country – then he lied about it to cover their tracks.
As detailed in The Sun, the confession is part of Lily's autobiography, My Thoughts Exactly.
In it, he writes: "We were hammered on the plane." At one point Liam and I found ourselves together in the bathroom doing something they should not have done, and they were not drugs, then we were together in a lying bed.
"When we disembarked in Tokyo, Liam said, in his characteristic nasal tone," What are you doing now? Why do not you come back to our hotel. . . I was like, "Yes, OK."
Conveniently, she insists that she has no idea of being married to Nicole – even though their union was major news at the time.
"It was not until the next day, when he said something like" You can not know about this because of Nic ", that I figured he was married." I knew Noel was married and I knew that Liam had been married to Patsy Kensit That was partly why I imagined I grew up an Oasis fan, I was 12 when he and Patsy Kensit were on the cover of Vanity Fair as the most beautiful couple. "
Unfortunately, Lily adds that Nicola knew about the accident – which resulted in a very embarrassing phone conversation.
Specifically, Liam asked her to lie and to say that nothing happened. What she did.
Unfortunately, the rocker's marriage has still collapsed after having slept with the New York journalist, Liza Ghorbani, who – shock, horror! – got pregnant and had the millionaire's son.
As if by magic she asked for a dollar to support her children.
Lily's last admission comes after Lily reveals that Coldplay's Chris Martin has staged an operation to consume alcohol and drugs.
Explaining his motivations for the book on Instagram, he recently stated: "Sooo, in my book detail some things from my dark days, around the era of Sheezus, I slept with female escorts when I was on tour, because I was lost and lonely and looking for something.
"I'm not proud, but I'm not ashamed … I do not do it anymore I just wanted to give you Er, the" head to head "."
