Australian actress Rebel Wilson shared, in a Monday morning Instagram story, that Sasha Baron Cohen was the "a--hole" she'd previously referred to in social media posts, saying that she would not be "bullied or silenced by high-priced lawyers or PR crisis managers."

Wilson's revelation comes in the wake of a previous Instagram post she'd made while promoting her new memoir "Rebel Rising." The "Pitch Perfect" star said that Chapter 23 of the forthcoming book was devoted to an "a--hole" that she worked with in the entertainment industry.

"When I first came to Hollywood, people were like, yeah, 'I have a no-a--hole policy, [it] means like, yeah, I don't work with a--holes.' I was like, 'Oh yeah. I mean, that sounds sensible or logical,'" Wilson, 44, said in a video shared to the social media platform on March 15.

"But then it really sunk in because I worked with a massive a--hole and yeah, now I definitely have a no-a--holes policy."

In subsequent social media posts, Wilson claimed that the star in question had hired a crisis public relations team to handle her accusations. Despite this, Wilson publicly confirmed the individual's identity.

"The 'a--hole' I am talking about in ONE CHAPTER of my book is: Sasha Baron Cohen," she shared, along with a photo of her memoir's manuscript.

Cohen, 52, has been subject to controversy in the past - with some critics arguing that his satirical characters, like Borat, are racist.

This is not the first time that Wilson has spoken out about her experiences with Cohen. Wilson played Cohen's girlfriend in the 2016 film "The Brothers Grimsby" and following that experience, she told the Australian media that he harassed her on set.

Wilson alleged that Baron insisted on inserting explicit sexual content into their scenes together and also pressured the actress to take her clothes off, on camera.

"Every day he's like, 'Just go naked, it will be funny. Remember in Borat when I did that naked scene? It was hilarious,'" Wilson told the radio show Kyle and Jackie O, in 2014. "On the last day I thought I'd obviously won the argument, and he got a body double to do the naked scene."

Cohen's camp refuted Wilson's comments in a statement to the Hollywood Reporter.

"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 spokesperson said.
