Rebel Wilson names Sacha Baron Cohen as ‘a**hole’ she has written about in new memoir

Rebel Wilson has named Sacha Baron Cohen as the “a**hole” who she has written about in her upcoming memoir.

The Australian actress and comedian, 44, previously said she intended to write a chapter in the book about “a massive a**hole” she had previously worked with in Hollywood – though she did not reveal the person’s identity.

However, in a post on Instagram on Monday, Wilson said the person she was referring to was Ali G and Borat star Baron Cohen.

“I will not be bullied or silenced by high-priced lawyers or PR crisis managers,” she wrote.

“The ‘a**hole’ I was talking about in one chapter of my book is: Sacha Baron Cohen”.

In a previous now-deleted Instagram story – reported on by Us Weekly – Wilson accused Baron Cohen’s team of “trying to stop press coming out about my book”.

“But the book WILL come out, and you will all know the truth,” she reportedly wrote.

Baron Cohen, 52, worked alongside Wilson on the set of his 2016 spy action comedy Grimsby, also known as The Brothers Grimsby.

In the film, the British comedian starred as the main character, alcoholic football hooligan turned elite spy, Nobby, while Wilson played Dawn Grobham, Nobby’s wife and mother to their 11 children.

The film also starred Mark Strong, Penelope Cruz, and Baron Cohen’s real-life wife, Isla Fisher.

Her upcoming memoir, named Rebel Rising, is due to be published next month.
