Rebel Wilson reveals Sacha Baron Cohen is the ‘a**hole’ she refers to in her explosive new memoir… after claiming previously unnamed star had ‘called in the lawyers’ over forthcoming book

Rebel Wilson has named British actor and comedian Sacha Baron Cohen as the celebrity responsible for making threats over her no-holds-barred memoir, Rebel Rising.

The Australian actress, 44, originally claimed she was facing possible legal action after dedicating an entire episode to a difficult work experience with an unnamed former co-star, whom Wilson called a “douchebag.”

It has since confirmed that the actor in question is Cohen, 52, best known for his comedy creations Ali G and Borat, with whom he starred in the 2016 action comedy Grimsby.

On Sunday she wrote on Instagram: “I will not be silenced by expensive lawyers or PR crisis managers. The idiot I talk about in ONE CHAPTER of my book is: Sacha Baron Cohen.

The post came just two days after the Pitch Perfect star alleged that a celebrity she once worked with was threatening her over the publication of the memoir.

“I wrote about a dick hole in my book,” he told his Instagram followers. ‘Now,’ he said, a ****** is trying to threaten me. He has hired a crisis public relations manager and lawyers.

He’s trying to stop the press from talking about my book. But the book will come out and you will all know the truth.’

In an Instagram video shared on March 15.Wilson revealed that he has dedicated a chapter of his book to the ‘huge jerk’ he worked with in Hollywood.

The Pitch Perfect star also claimed she would eventually name the male colleague whose alleged behavior led her to adopt a “no idiots policy” on set.

She wrote: “When I first came to Hollywood, people were like, ‘Yeah, I have a no-assholes policy, which means I don’t work with assholes.’ I was like, ‘Yeah, I mean, that sounds sensible and logical.’ “.

“But then I really understood what they meant by that, the older people in the industry. Because I worked with a huge asshole and, yeah, now I definitely have a no-asshole policy.

“Chapter one said asshole; it’s chapter 23, that guy was a huge asshole.”

And he added: ‘Do you want to know who is the biggest idiot I’ve ever worked with in Hollywood? Chapter 23 lists it all! Do you want to know why I now have a “no assholes” policy with the people I work with?

‘I wrote about an asshole in my book. Now, he said a ****** is trying to threaten me. He has hired a crisis public relations manager and lawyers.

‘Well, it’s all in the book: REBEL RISING available for pre-order now (available April 2, link in bio)… Oh, and YES, I name the sucker!’

Wilson and Cohen starred together in Grimsby alongside Mark Strong, Gabourey Sidibe and Isla Fisher, Cohen’s wife of 14 years.

The film was harshly criticized and currently has a 34 percent poor rating from the most prestigious critics surveyed by rotten tomatoes.

It was also a disappointment at the box office, only grossing around $28 million against a budget of $35 million, according to box office mojo.
