LILY ALLEN’S tell-all book is just days away from hitting the shelves and already the revelations are coming thick and fast.

First we learned she will detail the time she joined the Mile High Club with Liam Gallagher.

Next, that she had a fling with bitter rival Mike Skinner of rap act The Streets during the height of their feud.

And this weekend, with unflinching honesty, came the most extraordinary bombshell yet — that the 33-year-old mum-of-two hired lesbian vice girls for sex on tour.

Lily wrote on Instagram: “I was lost and lonely and looking for something. I’m not proud but I’m not ashamed.”

It is no surprise then that showbiz friends and industry bigwigs are quaking in their boots with just 18 days to go until the publication of My Thoughts Exactly.

If Lily can be so brutally honest about herself, what on earth will she say about them?

She has been on the pop scene since her breakthrough album Alright, Still in 2006, attended hundreds of parties, hung out with the biggest stars and taken drugs with a lot of different people.

The singer has openly admitted she took drugs for the first time aged 13 when she was at Glastonbury.

Then at the festival in 2015 she headed out of a tent, sat down on the grass and promptly collapsed. An onlooker told us: “She was out of it, she didn’t know where she was.”

The following summer she was again the worse for the wear at the Notting Hill Carnival. She vomited, collapsed and needed a fireman’s lift from a friend after necking Jack Daniel’s, a can of Strongbow and smoking a joint.

Nor will this be the first time Lily has admitted enjoying the romantic affections of other women.

She told Gay Times in 2009 that she once had a lesbian threesome with identical twins.

Now, with a career in the doldrums — her last album No Shame was a flop — she has little left to lose.

Even her dad, the comedy actor Keith Allen, is worried, having walked out on the family when Lily was four.

The 65-year-old said: “I’m not made of steel. But I have read stuff that Lil’s said about me and I’ve thought, ‘Really? Hang on a minute. That’s not my memory, not quite.’

“But it’s tricky. Me, in her eyes, abandoning the family, is a big thing.”

He also stressed Lily’s brother Alfie, star of Game Of Thrones, is “very worried” about what confidences his sister will share. But who else could be feeling the heat?

Her former drinking buddies from the late Noughties, including Strictly’s Daisy Lowe, Bake Off’s Noel Fielding and Radio 1 host Nick Grimshaw, must be praying she is prepared to forgive and forget those nights on the razzle.

Few have more to lose than Adele. Back in 2008, the chart queen was there when Lily celebrated her 23rd birthday at Claridges hotel and drank with her at the 2012 Brit Awards.

But since Adele’s stratospheric rise the pair have drifted apart, with Lily branding the icon a “bitch” and bemoaning her career in the US.

Other victims of the acid-tongued singer’s jibes include Cheryl Tweedy, of who Lily once said: “I hate her guts. She’s a horrible, nasty, disgusting human being.”

Katy Perry was told: “You don’t write your own songs, shut up,” Elton John was blasted with: “F*** off Elton. I am 40 years younger than you and have my whole life ahead of me” and Bob Geldof was labelled a “sanctimonious prat”.

Even Victoria Beckham got it in the neck, with Lily saying: “She gives a bad image to children. No one should be that skinny.” Lily has admitted she was sleeping with escort girls around the time she released her album Sheezus in 2014.

The singer was in the depths of marital misery at the time, going on to split up with builder Sam Cooper in 2016 after five years of marriage.

Lily, who has daughters Ethel, six, and Marnie, five, said of the time: “I was being a bad mum. I was being bad at my job. I’d wake up on a tour bus in the middle of Wisconsin and be so hungover. I cheated on my husband.”

Around the same time, another former close friend and drinking buddy was on the brink of superstardom. In 2015, James Corden became the host of The Late Late Show in the US.

They were regularly photographed together and last year Lily claimed James “came on to her” during a TV interview in 2008 after a Twitter user unearthed old footage from the singer’s failed BBC Three chat show Lily And Friends.

During the segment, Lily complimented Corden’s “dazzling eyes”, while the actor replied: “I don’t think you know how lovely you are.” She later said: “I wasn’t horny for James, he came on to me in front of a studio audience.

“If I’d have shut him down I would have been labelled cold or up myself or snobbish.”

James has always said that Lily made the first move. In his autobiography he claimed the star asked for his number after meeting him at a film premiere in 2006.

Lily is also expected to detail her secret fling with Mike Skinner.

A widely reported “source” said last month: “What they managed to both keep out of the public domain was they had once seen each other at a showbiz bash, got a bit tipsy . . .  and one thing led to another.”

Lily later ridiculed The Streets frontman for having a “2in” penis.

In 2012, TV host Fearne Cotton revealed Lily “doesn’t like me” and added: “Literally never spoke to her, but she has a pop at me.”

Two years later she claimed Lily snubbed her at the Brit awards.

In 2008, Bake Off presenter Noel Fielding got thrown out of a London nightclub with Lily. The pair, along with Razorlight frontman Johnny Borrell, were turfed out by bouncers after Lily drunkenly visited the men’s toilets with both men.

In more recent years she has partied with One Direction stars Liam Payne and Harry Styles, as well as Miley Cyrus and Cara Delevingne.

And now, every celebrity she has ever taken drugs with must be trembling at the thought of the out- spoken star revealing their secret demons.

She once said: “A lot of people I know are drug addicts. So they’re not much fun, because they’ll just talk at you very loudly about things you don’t feel nearly as passionately about.

“There’s a lot of self-delusion. I was in the toilet, a long time ago, with this person when they said, ‘I’ve been clean for nearly ten years.’ And I’m like, ‘What do you think we’re doing here?’ ” Lily’s book is also expected to lift the lid on her own damaging relationship with drugs and alcohol.

She admitted recently: “I think I’m a raging co-dependent and then when I feel like I can’t cope, I abuse alcohol and drugs to plaster over some stuff, but I’ve never been somebody that craves a fix.”

Earlier this year she confessed to Twitter followers about her drug-fuelled night out at the 2008 Glamour Woman of The Year Awards.

Thomas ‘punch’
It is hardly the sort of occasion where someone would anticipate hitting hard drugs, but Lily confessed: “Someone gave me a line of what I assumed to be cocaine but it turned out to be ketamine.

“I was thrown out — passed over some railings — for being in a k-hole.”
Her former pals must be hoping that, although fun, those heady years of partying have made more than just a mild dent in her long-term memory.
