Lily Allen “ended up kissing” Zoe Kravitz at a party in 2014, whilst still married to her then-husband Sam Cooper

Lily - who has Ethel, six, and Marnie, five, with her now ex-husband Sam - wrote in the excerpt which was obtained by The Sun newspaper’s Bizarre column: “For my New York shows, Zoe Kravitz and her band Lolawolf supported me, so I got to know Zoe a bit. We became friends.

“Later in the tour, when we were in Washington, the girls 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 A$AP Rocky. Go girl, I thought.”

The ‘Trigger Bang’ hitmaker also claims she almost got it on with Orlando Bloom at a Halloween party that same year.

She wrote: “Orlando was famous long before I was, and when I first got to know him I think he felt protective of me. But, not any more, he didn’t.

“He’s a flirt, Orlando. He knew I was up for it at that party. He was, too.”

Lily claims the pair never ended up getting together because she was so drunk she knocked herself out.

The racy confessions come after a previously released excerpt from the upcoming book revealed the ‘Not Fair’ singer had slept with former Oasis frontman Liam Gallagher on a plane to Japan for the Fuji Rock Festival in 2009, whilst he was still married to Nicole Appleton.

She wrote: "We got hammered on the plane. At some point Liam and I found ourselves together in the toilet doing something that he shouldn't have been doing, and it wasn't drugs. Then we were in a lie-down bed together.

"When we landed in Tokyo, Liam said, in his distinctive nasal twang, 'What you doing now? Why don't you come back to our hotel'?.?.?.? I was like, 'Yeah, OK'."
