Rebel Wilson has claimed a member of the Royal Family invited her to a drug-fuelled orgy at the home of a US tech billionaire.

The Australian does not name the royal, but gives three hints: he is male, it happened in 2014 and he was ‘fifteenth or twentieth in line to the British throne’.

In her memoir, Rebel Rising, she tells how she got ‘a last-minute invite to a tech billionaire’s party’ from the royal who had told a male friend, ‘We need more girls’.

‘What a perfect opportunity to find a boyfriend, I thought.’

According to the book, the medieval-themed party was held at a rented ranch just outside Los Angeles.

In her new memoir Rebel Rising, Wilson says she wore a ‘buxom damsel outfit complete with cone hat’ – which complemented her ‘child-bearing hips’ – and describes the event as ‘insane’ with acrobats mingling with the crowd and a giant firepit surrounded by cushions

Wilson says she wore a ‘hearty maid outfit total with cone cap’ – which supplemented her ‘kid bearing hips’ – and portrays the occasion as ‘crazy’ with tumblers blending with the group and a monster firepit encompassed by pads.

She says she addressed the tycoon, who is likewise anonymous, that evening yet who successfully ‘blanked’ her.

At the party, she guarantees, men were jousting on ponies in a field and there was a pool brimming with young ladies dressed as mermaids.

In view of the tremendousness of the house and its confined area, visitors were doled out rooms to stay in bed for the time being.

The Australian-conceived star of Pitch Awesome and Bridesmaids portrays seeing the anonymous minor English regal there and medications straightforwardly being given around on plate, composing: ‘I watch the English regal struggle around while I ceaselessly climb up my boobs.

‘They are my best physical asset, I think… There’s a huge private fireworks display and then all of a sudden, it’s 2am and a guy comes out with a large tray piled with what looks like a ton of candy.

‘I’m like, ‘Oooh, is that candy?’ And the guy holding the tray says, ‘No, this is the molly [or MDMA, another word for the drug ecstasy],’ and I turned to the screenwriter I’ve been talking with, confused. He says, ‘Oh, it’s for the orgy….the orgies normally start at these things about this time’.’

The actress conveys her shock at the suggestion, saying: ‘Now the comment by the Windsor about needing more girls started to make a lot more sense.’

Wilson’s memoir has already been embroiled in controversy after making allegations about the behaviour of British comic Sacha Baron Cohen during the filming of their 2016 comedy Grimsby in the US version of the book. He strongly denies this

She claims earlier in the book that ‘the guy who invited me, who’s like fifteenth or twentieth in line to the British throne, had said to my male friend, ‘We need more girls’.

‘They weren’t talking about a boy-girl ratio like it was a year-eight disco. They were talking about an ORGY!’

Wilson writes that she was a virgin at the time and couldn’t shake the feeling that the party may have been filmed by hidden cameras.

‘Needless to say, I hike up my damsel dress and run out of there as fast as I can.’

The actress also claims that ‘around the same time’ she was offered $2 million to spend the weekend ‘with some Jordanian prince’.

She said she ‘asked around the industry’ about what that kind of offer would entail and was told that she would be expected ‘at some point to sleep with the prince’.
