The former stable girl who took Prince Harry's virginity claims she wasn't warned about their tryst being aired in his blockbuster memoir Spare - and only found out through WhatsApp.
Mum-of-two Sasha Walpole, 40, who is just two years older than the Duke of Sussex, has admitted the liaison happened after a boozy night in which they drank ten shots of tequila, Baileys and sambuca.
In his best-selling memoir, Harry said he lost his virginity to a mysterious older woman when he was just 17.
Sasha - who argues that Harry was 16 at the time - said the liaison was "wham-bam between two friends" and "passionate and sparky because we shouldn't have been doing it".
The encounter happened behind the Vine Tree Inn in Wiltshire back in July 2001 after Sasha's 19th birthday party.
Sasha has shared spicy details of the night because she was shocked that Harry mentioned it in Spare, for which he was paid £17 million in advance and has sold 3.2million copies to date.
She revealed how she was told that incidents in her past were being shared with the world after a friend warned her on WhatsApp.
Sasha told The Sun on Sunday: “No one warned me about the night being included in the book - and Harry, or his people, could have found me to tell me if they had wanted to do so.
“I lead a peaceful life — I didn’t invite this.”
Speaking in the Mail on Sunday, she added: "I kept this a secret for 21 years. I did it because Harry was a friend, regardless of whether he's a Prince or not.
"I didn't invite any of this attention, but I know the hunt would have kept going until people found me. I don't understand why he went into such detail [...] He described how it happened – in a field behind a pub.
"That's fine if you're not the other person involved. But if you're me, then you suddenly feel as if your world is getting a little bit smaller."
During one interview, she inferred that Harry was "above average" and that she had pinched his "peachy bum" after the tryst.
Sasha - who knew Harry after working as a stable girl at Highgrove - said the attraction came from the pair being "purely friends and it was a little bit naughty".
She admitted feeling it shouldn't have happened and that the night had got out of control.
The encounter happened the night after Harry enjoyed a trip to Thorpe Park in Surrey with pals.
Sasha - whose Highgrove contract had finished - had completed a shift at a lingerie factory and said she was upset after breaking up with her first love. Her ex then showed up at the pub with his new girlfriend.
Considerate Harry bought them a round of five shots each with the hopes of lifting the mood, which they downed immediately.
At around 11pm, Harry asked Sasha to go outside to share a cigarette, swerving his security detail and jumping over a fence into the field where they would have sex.
By the time they were finished, Harry's minders were hunting him down and eventually one of Sasha's pals drove up in a Ford Fiesta with a security officer in the passenger seat.
Later, Sasha realised that she must have taken his virginity because she knew he hadn't had sex with anyone else before.
After the liaison, Sasha never saw Harry or spoke to him again, not even over text - but she says she's not phased.
