REBEL Wilson has dropped three tantalising hints as to the identity of the mystery royal she claims invited her to a drug-fuelled orgy at a US mansion.

The member of the British Royal Family has not been named by the Aussie actress, 44, but she revealed some clues in her newly-released memoir Rebel Rising.

In the book, which has already proved to be highly controversial, the star of Pitch Perfect claims it was a male, it occurred in 2014 and he was something like “fifteenth or twentieth in line to the British throne”.

She says she got a “last minute invite to a tech billionaire’s party” from the royal who had told a pal: “We need more girls.”

The party, held at a ranch outside of Los Angeles, had a medieval theme.

‘Buxom’ for billionaire’s party

She thought the party would be a “perfect opportunity to find a boyfriend”.

The Hollywood actress said she wore a “buxom damsel outfit complete with cone hat” which she though complemented her “child-bearing hips”.

Rebel described the party as “insane” with featured acrobats mingling with the crowd and a giant firepit surrounded by cushions.

There were also men jousting on horses in a field and the swimming pool was filled with girls dressed as mermaids.

She claims to have spoken with the billionaire, whose identity is also not revealed, at the party but who effectively “blanked” her.

Due to the location of the ranch and its isolated location, guests were given rooms to sleep in for the night.

The star of the movie Bridesmaids says she saw the British royal at the party and drugs were being openly handed around on trays.

Rebel wrote: “I watch the British royal flounder around whilst I continuously hike up my boobs. They are my best physical asset.”

Following a firework display, she said a man appeared holding a tray of what appeared to be sweets but were actually the drug MDMA.

When she asked what they were for, the unnamed man replied: “Oh, it’s for the orgy… the orgies normally start at these things at about this time.”

They were talking about an ORGY!

In the book, she said: “Now the comment by the Windsor about needing more girls started to make a lot more sense.”

She wrote: “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!”

Rebel also added she was a virgin at the time and couldn’t dismiss the feeling the party may have been filmed by hidden cameras.

She wrote: “Needless to say, I hike up my damsel dress and run out of there as fast as I can.”

Rebel also claims that she was also offered $2million to spend the weekend “with some Jordanian prince” at “around the same time” as the party.

She said she “asked around the industry” about what exactly the offer would entail and was told she would be expected “at some point to sleep with the prince”.

Sacha blast

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

She accused the Ali G star of “humiliating and degrading” her on the set of 2016 film and said “the truth will come out”.

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.

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.
