Sacha Baron Cohen is calling accusations Rebel Wilson made against him in her upcoming memoir demonstrably false.

On April 2, the Pitch Perfect star will release Rebel Rising a book she stated last month will include a chapter dedicated to a massive asshole she once worked with.

Over the weekend, Wilson revealed in an Instagram story that the person she was referring to was Cohen, with whom she co-starred in the 2016 spy comedy The Brothers Grimsby, a film Cohen co-wrote. In the post, Wilson also stated Cohens team of high priced lawyers and PR crisis managers are now trying to threaten her ahead of the release of her memoir.

On Monday, the Ali G comedian responded to the allegations in a statement to Deadline .

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, Cohens statement read.
