With her first tell-all memoir officially out, Rebel Wilson put all her cards on the table. From talking about her relationship history to her complicated dynamic with a co-star, Wilson opened up to the world for the first time in her new memoir,Rebel Rising.

In one of the most shocking stories in the book, Wilson remembered working with comedian Sacha Baron Cohen in the 2016 comedy The Brothers Grimsby. Among the absurd things Cohen allegedly did was pressuring her to streak in the film and asking her to stick a finger up his butt in one scene. “I was now scared,” Wilson wrote, per Entertainment Tonight. “I wanted to get out of there, so I finally compromised: I slapped him on the a– and improvised a few lines as the character.”
