Lily Allen has claimed in her bombshell autobiography My Thoughts Exactly that she kissed Zoe Kravitz in 2014.
The British singer has been extremely candid about her struggles that year in her upcoming book, with earlier revelations including her problems with alcohol and sleeping with female escorts while on tour despite being married to husband Sam Cooper at the time.
More confessions have now emerged, with Britain's The Sun newspaper reporting that mother-of-two Lily, 33, spills all about the time she kissed actress/singer Zoe, the daughter of rocker Lenny Kravitz and actress Lisa Bonet, at a party.
"For my New York shows, Zoe Kravitz and her band Lolawolf supported me, so I got to know Zoe a bit. We became friends," she wrote. "Later in the tour, when we were in Washington, the girls (Lily's daughters) and their nanny, Jess, came out to visit me for a few days, but I had to go back to New York for a day or so for work.
"Zoe and I went out partying and ended up kissing. I heard that later that same night she'd got down with (rapper) A$AP Rocky. Go girl, I thought."
The Smile singer mentions plenty of celebrities in her book, which is released later this month (Sep18), revealing that both she and British actor Orlando Bloom were "up for it" at a 2014 Halloween party, but she got so drunk she knocked herself out, so Coldplay's Chris Martin took her home and subsequently made her realise she needed help.
She has also made shocking allegations about Oasis star Liam Gallagher, who she claims she slept with in a plane toilet before going to his hotel in Japan in 2009, when he was married to Nicole Appleton.
She claimed she didn't know he was married until he asked her to kept their fling a secret. He also allegedly asked her to cover it up after Nicole found out six months later.
"'Lil,' he said. "I just need you to get on the phone. I've got Nic here. One of your mates is, like, trying to do a wind-up or something and saying that you and me had it off or whatever, and I need you to speak to Nic and say that it's all b**locks,'" Lily wrote in the book.
