‘Scared’ Rebel Wilson claims Sacha Baron Cohen wanted her ‘to go naked’ on set in bombshell memoir excerpt

But wait … there’s more.

A new excerpt from Rebel Wilson‘s memoir has been revealed, in which she describes in detail her alleged interactions with Sacha Baron Cohen as they worked on 2016’s “The Brothers Grimsby.”

Wilson, 44, said that she initially met Cohen, 52, during a dinner party in 2013 and was later asked by the “Borat” star to play his girlfriend, Dawn, in the ill-fated, R-rated comedy.

“It felt like every time I’d speak to SBC, he’d mention that he wanted me to go naked in a future scene,” the “Rebel Rising” excerpt read, which was obtained by People on Wednesday. “I was like, ‘Ha, I don’t do nudity, Sacha.’ “

Despite her refusal, co-writer Cohen seemed determined to get his nude scene.

While shooting in Cape Town, South Africa, the “Pitch Perfect” actress claimed she was summoned by Cohen “via a production assistant” saying she was “needed to film an additional scene.”

” ‘Okay, well, we’re gonna film this extra scene,’ SBC says. Then he pulls his pants down … SBC says very matter-of-factly: ‘Okay, now I want you to stick your finger up my ass.’ And I’m like, ‘What?? … No!!’ ”

“I was now scared,” the actress said. “I wanted to get out of there, so I finally compromised: I slapped him on the ass and improvised a few lines as the character.”

After shooting the bizarre scene, she immediately contacted her agent and a lawyer and was “encouraged to ‘be professional and finish the film.’ ”

The “Struck by Lightning” star tried to cope with Cohen’s alleged behavior by trying “to laugh it off.”

However, Wilson’s resolve began to crumble when she was asked to do several reshoots — which included a sex scene.

“I filmed the scene, after demanding rewrites,” she wrote. “But I still had to simulate having sex with this guy. I still had to kiss him repeatedly.”

“It really sank in that all this wasn’t something that could be laughed off,” Wilson wrote. “I relayed to the producers that I would not be doing any promotion for the film.”

The movie, which has a 36% on movie and TV-review website Rotten Tomatoes, subsequently bombed at the box office, which was “karma enough” for Wilson.

“I’m not about canceling anybody and that’s not my motivation for sharing this story,” Wilson wrote, per People. “I’m sharing my story now because the more women talk about things like this, hopefully the less it happens.”

Since the allegations against him first emerged on Monday, Cohen has vehemently denied ever mistreating Wilson or pressuring her to film any type of lewd scene.

“While we appreciate the importance of speaking out, these demonstrably false claims are directly contradicted by extensive detailed evidence, including contemporaneous documents, film footage and eyewitness accounts from those present before, during and after the production of ‘The Brothers Grimsby,’” a spokesman for the “Dictator” star told The Post.

According to People, the comedian’s reps also provided nine anonymous statements from the film’s crew who claim they were present at the shoot and Wilson was never mistreated.

“As per the script, which Rebel had read and approved in advance, her character was attempting to put a finger in Sacha’s character’s butt. At no point did Sacha actually ask her to put a finger in his butt,” one alleged producer said. “Throughout this entire period, she was treated with the utmost respect and empowerment and was welcomed as a collaborator in all creative areas.”

One writer-producer claimed that it was “a scheduled, scripted scene.”

Wilson previously revealed she dedicated an entire chapter of her memoir — set to hit stores on April 2 — to a Hollywood star she labeled a “massive a – – hole.”

After revealing it was Cohen, she insisted she would not be threatened or silenced by him.
