Rebel Wilson Claims Sacha Baron Cohen Is Hollywood 'A--hole' 'Trying to Threaten' Her, Block Memoir

"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."

After teasing out the identity of an unnamed "a--hole" she claims to have worked with in the past, Rebel Wilson went ahead and revealed who it was ahead of the release of her upcoming memoir.

"I will not be bullied or silenced by high priced lawyers or PR crisis managers," Wilson wrote in a new update on her Instagram Stories. "The 'a--hole' that I am talking about in ONE CHAPTER of my books is: Sacha Baron Cohen."

The comedian, best known for portraying the fictional characters Borat and and Ali G, worked together on the 2016 Grimsby film (released in the US as The Brothers Grimsby), with Wilson portraying the girlfriend of Cohen's characters.

As noted by The Hollywood Reporter, Wilson had previously spoken up about her filming experience with Cohen on the film in 2014, telling Australia's Courier and Mail that "every day" he'd ask her to "go naked" for a scene. She said she even threatened to tell their shared American agent "how much you are harassing me."

She thought she'd won that ongoing argument when the film used a body double for the final scene. "Then in the last scene ... he was like, 'Rebel can you just stick your finger up my butt?' And I went, 'What do you mean Sacha? That's not in the script.' "And he's like, 'Look, I'll just pull down my pants, you just stick your finger up my butt, it'll be a really funny bit."

According to the newspaper, Wilson settled on a compromise with Cohen's character, slapping him on the butt instead. TooFab has reached out to a representative for Cohen for comment.

According to Rebel Wilson, one former co-star is pulling out all the stops to try and stop her book's release -- while also hiring "a crisis PR manager and lawyers" -- and has even gone so far as to threaten her.

The actress took to her Instagram Stories with a slide hinting at the actor's response to her prior comments that her forthcoming memoir, Rebel Rising, will detail her encounters with a "massive a--hole" earlier in her career, and she's going to name names.

"I wrote about an a--hole in my book. Now, said a--hole is trying to threaten me," she wrote on her Instagram Stories over the weekend, as captured by Us Weekly. "He's hired a crisis PR manager and lawyers. He is trying to stop press coming out about my book."

"But the book WILL come out and you will all know the truth," Wilson concluded her message.

Earlier this month, on March 15, the comedian had teased that she would reveal the identity of this "a--hole" in an Instagram video. In it, she said she first learned of people's "no a--hole" policies when she moved to Los Angeles.

"Then it really sunk in what they were meaning by that," she said, "Older people in the industry." Wilson went on to say she now has the same policy, noting that Chapter 23 will focus on the one that caused her to implement the policy. "That guy was a massive a--hole," she said.

While it's not clear if the "a--hole" in her memoir is the same person she's been alluding to for years, Wilson had made a previous claim amid the MeToo movement, about an extremely inappropriate sexual encounter she had with "a male star, in a position of power."

Warning: the following allegations are graphic and may be disturbing.

In a since-deleted post to her X/Twitter account from November 2017, per Us Weekly, Wilson wrote that said star "asked me to go into a room with him and then asked me repeatedly to stick my finger up his a--. All whilst his male 'friends' tried to film the incident on their iPhones and laughed. I repeatedly said no and eventually got out of the room."

Wilson has never named names for this alleged incident, but said she did file a complaint at the time with the studio. She continued at the time saying she was later "threatened by one of the star's representatives to be ice and support the star," which she refused to do. "The whole thing was disgusting."

Rebel Rising is set for release on April 2.
