Ahead of the release of her forthcoming memoir, Rebel Wilson is opening up about one of the lowest moments of her career.

Wilson told The Sunday Times in an interview published over the weekend that filming 2016s The Brothers Grimsby alongside Sacha Baron Cohen , who starred in the movie and was also one of its producers and writers, was the worst professional experience shes ever had.

The Pitch Perfect star said that she felt disrespected on set because of the way the movie was both shot and written for her character.

Its one thing for someone who is fat to exploit their size for comedy, but its another for somebody else to humiliate you, Wilson said.

She also shared that her costumes appeared to be designed to see all the cellulite on my thighs and a top to show the fattest part of my arm and make her something to be laughed at and degraded because of my size.
