HOLLYWOOD actress Rebel Wilson claims an unnamed member of the Royal Family invited her to a medieval-themed drug-fuelled orgy.

The Aussie star, 44, fails to name the man in her shock allegation but claims he was a “Windsor” and something like “fifteenth or twentieth in line to the British throne”.

The mystery royal allegedly told the actress: “We need more girls”.

She described being offered a tray of MDMA ahead of an orgy at a party held at a ranch owned by a US tech billionaire just outside Los Angeles in 2014.

Writing in her memoir Rebel Rising, she claimed: “I got thrown a last-minute invite to a tech billionaire’s party – 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’.”

Wilson says she wore a “buxom damsel outfit complete with cone hat. It was a vibe.”

She recalled: “The party was insane. Men were jousting on horses in a field, girls dressed as mermaids were in the pool.

“The property was massive, and because it was quite a drive, people had been assigned rooms to sleep there overnight.”

The Pitch Perfect star added: “I watch the British royal flounder around whilst I continuously hike up my boobs.

“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, ‘Ooooh, is that candy?’ and the guy holding the tray says, ‘No, this is the molly [MDMA],’ 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.'”

“Now the comment by the Windsor about needing more girls started to make a lot more sense. They weren’t talking about a boy-girl ratio like it was a year-eight disco. They were talking about an ORGY!”

Hollywood’s Power Couple Splits: Sacha Baron Cohen and Isla Fisher’s Divorce

It comes after Rebel Wilson slammed Sacha Baron Cohen in her memoir for his alleged behaviour on the set of The Brothers Grimsby.

The Sun understands Rebel’s claims were a catalyst for Isla Fisher to publicly reveal her split from Sacha.

The claims against the unnamed royal are the latest bombshell to hit the family.

The Bridesmaids actress has suffered a huge blow after tickets for her forthcoming tour dates have been slashed by a whopping 75 per cent just days before it hits the UK.

Ms Wilson and her team are quietly advertising the knocked down priced tickets for her upcoming show at Manchester’s Opera House.

On seat filling website ShowFilmFirst, in a last minute bid to boost sales, fans are able to purchase tickets for just £16 rather than the original price of £67.

It follows rumours that there have been problems trying to shift tickets to Rebel’s In Conversation event on April 26.

Rebel’s tour – which is to promote her controversial tell-all memoir, Rebel Rising – is due to visit Manchester, London and Edinburgh later this month.

The actress was also due to hold events in Australia but was forced to cancel them due to scheduling conflicts.

The ShowFilmFirst website, which is hugely popular with artists and theatre shows wanting help with selling tickets for their tours, allows a closed group of people access to tickets for a fraction of the original price as a last minute option to fill up empty seats.

Shamed Prince Andrew, 64, paid millions of pounds in an out-of-court settlement to Virginia Giuffre who accused him of 𝓈ℯ𝓍ual abuse.

Prince Harry, 39, admitted taking magic mushrooms, cocaine and cannabis in his shock memoir Spare.

Buckingham Palace declined to comment.
