Rebel Wilson hasn’t spoken to Isla Fisher since she made her bombshell claims about Sacha Baron Cohen in her memoir 'Rising Rebel'.

The 44-year-old actress branded her 'Grismby' co-star, 52, a "massive a******" in her book just before Sacha and his wife Isla announced their divorce, and Rebel has admitted she hasn’t reached out to her friend yet.

During an appearance on the 'The Kyle and Jackie O Show' where she was asked if she has been in contact with the 'Wedding Crashers' actress, Rebel said: "I haven’t spoken to her.

"Obviously, I used to be friends with her before all this happened. We did a movie together called 'Bachelorette'."

The 'Pitch Perfect' actress made her claims about Sacha just a week before he and Isla announced their divorce – where the couple revealed they had been separated since 2023 after 13 years of marriage – though Rebel has insisted her comments had nothing to do with their split.

She said: "I don’t feel like I'm the reason [for the break up]. But it might have been just his general treatment to women."

In her memoir, Rebel claims she felt "humiliated" after working with Sacha on their 2016 comedy 'Grimsby'.

Speaking at 'An Evening With Rebel Wilson' at the London Palladium, she said: "It was a bad experience and I felt humiliated and I had a bit of shame surrounding it because I should have left."

The 'Jojo Rabbit' star admitted that if she was "the person she is today", she would have walked away from the film there and then, and her experience spurred her on to open up about the allegations to help people "going through something" similar.

She explained: "I wanted to write the story for if anyone is going through something like that to give them perspective on it if they are feeling shame. It released some of that shame by writing about it."

After Rebel went public with her claims, Sacha denied all of the allegations.

He told The Independent newspaper: "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 'Grimsby'."
