‘Scared’ Rebel Wilson describes on-set humiliation by Sacha Baron Cohen in shocking memoir excerpt

“I still had to simulate having sex with this guy. I still had to kiss him repeatedly,” she writes.

“[Months later], it really sank in that all this wasn’t something that could be laughed off. I relayed to the producers that I would not be doing any promotion for the film.”

After calling the film’s lack of box office success “karma enough,” the actress insists she was “not about canceling anybody” by sharing her story.

“I’m sharing … now because the more women talk about things like this, hopefully the less it happens,” she explains.

Wilson, who shared similar on-set anecdotes about Cohen on the “Kyle & Jackie O” radio show in 2014, made headlines over the weekend when she named him as the “massive a–hole” she wrote about in “Rebel Rising,” out April 2.

“He’s hired a crisis PR manager and lawyers,” she told her Instagram followers. “He is trying to stop press coming out about my book. But the book WILL come out, and you will all know the truth.”

Cohen has since denied wrongdoing, with his rep telling Page Six the claims are “demonstrably false” and “directly contradicted by extensive, detailed evidence, including contemporaneous documents, film footage and eyewitness accounts from those present before, during and after the production.”

His spokesperson provided People with anonymous statements from people associated with the film, claiming Wilson “was treated with the utmost respect and empowerment and was welcomed as a collaborator in all creative areas.”

She has since doubled down on her allegations, writing via Instagram Tuesday that she will not “be threatened.”
