Rebel Wilson Reveals Name of A-List 'A**hole' She Has a Chapter About in Her Memoir

The actress worked with the actor on the 2016 film, 'The Brothers Grimsby.'

Rebel Wilson is refusing to be silenced. The 44-year-old Australian actress took to her Instagram Stories early Monday morning to release the name of an A-lister she refers to as an "a**hole" in her upcoming memoir

"I will not be bullied or silenced by high priced lawyers or PR crisis managers," Wilson wrote. "The 'a**hole' that I am talking about in ONE CHAPTER of my book is: Sacha Baron Cohen." 

Wilson and Baron Cohen co-starred in the 2016 film, The Brothers Grimsby, together. Baron Cohen, who shares three children with wife, Isla Fisher, and is best known for Borat, Brüno, Ali G and more, has not publicly commented on the claims.

Wilson's upcoming memoir, Rebel Rising, is being released on April 2. She previously teased naming the "a**hole," in a March 15 Instagram video. 

"When I first came to Hollywood, people were like, 'Yeah, I have a no a**hole policy. I don't work with a**holes.' I was like, 'Oh yeah, that sounds sensible, logical,' but then it really sunk in what they were meaning by that, older people in the industry," Wilson reflected. "Because I worked with a massive a**hole and, yeah, I definitely have a no a**holes policy. A chapter on said a**hole is chapter 23. That guy was a massive a**hole."

During a 2014 appearance on the Kyle and Jackie O on KIIS FM radio show, Wilson accused Baron Cohen of repeatedly asking her to do nude scenes in the film.

"Sacha is so outrageous," she said at the time. "Every single day he's like, 'Rebel, can you just go naked in this scene?' And I'm like, 'No!'" 

Noting that they had the same American agent, she added, "I'm like, 'Sacha, I'm going to call our agent, Sharon, and tell her how much you are harassing me." 

She said that though Baron Cohen hired a body double to perform the nude scene, she claimed at the time that he asked her to stick her finger up his butt in one scene. 

"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,'" Wilson alleged, noting that she refused. 

Rebel Rising will be released on April 2.
