Rebel Wilson hits back at Sacha Baron Cohen's claims about her book: ‘100% truthful’

Rebel Wilson shared her response to former co-star Sacha Baron Cohen’s reaction to her upcoming memoir, in which she called working with the "Borat" star her “worst professional experience.”

"Obviously, knowing his character, I assumed he would react in this way," Wilson told TODAY's Hoda Kotb on April 1. "Writing a memoir, the book gets fully legally vetted, so obviously, there are tons of people to back what I'm saying in the book. The book is 100% honest and truthful."

In a previous statement to NBC News, a representative for Cohen called Wilson’s allegations “demonstrably false” and “are directly contradicted by extensive detailed evidence."

Cohen’s rep said seven people who worked on the the 2016 film “The Brothers Grimsby” have come forward supporting his statement with documentation like call sheets and scripts that Cohen said contradict Wilson’s claims.

Wilson, 44, said on TODAY she thought her experience was worth including in her memoir, "Rebel Rising," because she felt other people might relate to what she allegedly went through.

"I mean, that was something that happened 10 years ago, and obviously I've moved past it now, but it was my worst professional experience ... just feeling like humiliated and degraded as a person," Wilson said.

"So, at least, to help some people feel not alone and to know that you can go through something like that at work, and then come out the other side as a stronger person," she continued.

Wilson, who appeared on TODAY one day ahead of the release of "Rebel Rising," called the book a "very deeply personal memoir."

"I'm feeling a mix of anxiety, because to be so vulnerable and to put it all out there, it does take a bit of courage to do that," she said.

"Now I guess it's just releasing it out into the world, which I guess is kind of cathartic in a way because it's just like, 'OK, here it all is," she added.

On social media last month, Wilson alleged Cohen was sending her legal threats ahead of the memoir's publication, and she thanked people who had sent her supportive messages on March 26.

"Thanks so much to everyone who has sent gorgeous messages of support in the last few days and to those who shared with me their stories of this a--hole! Don't worry I won't be bullied or threatened by this guy! And am working hard behind the scenes to make sure my book comes out!" she wrote in a post to her Instagram story.

Wilson added: "Ps my book is not ABOUT this guy - this is one chapter!"

TODAY.com did not hear back from Cohen’s rep for comment. TODAY.com has also not reviewed the book ahead of its release.

In an Instagram story on March 24, Wilson called Cohen, 52, an "a--" who was trying to "silence" her.

"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."

The "Pitch Perfect" actor previously alleged an unnamed "a---" was "trying to threaten" her, according to Variety and other news outlets.

"He’s hired a crisis PR manager and lawyers. He’s trying to stop press coming out about my new book. But the book WILL come out and you will all know the truth," she said, according to Variety.

Wilson and Cohen both starred in “The Brothers Grimsby,” a spy comedy in Cohen’s classic edgy style where Cohen’s character, Norman “Nobby” Butcher, realizes he has a long-lost brother who is a spy. Wilson plays Dawn, Nobby’s girlfriend, in the film.

After Wilson's initial post, a representative for Cohen called her allegations "demonstrably false" in a statement to TODAY.com.

"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."

Wilson first spoke of the controversy in a March 15 Instagram post while promoting "Rebel Rising," which publishes on April 2.

"When I first came to Hollywood, people were like, 'Yeah, I have a no a--hole policy,' (which) means like, 'Yeah, I don’t work with a--holes.' I was like, 'Oh yeah. I mean, that sounds sensible, logical,'" she said. "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."

Wilson continued promoting her book, saying Chapter 23 would contain more information about the alleged "massive a----."
