Halle Berry stuck her breasts in a "bowl of guacamole" on the set of her new movie, it has been claimed.

The actress shocked the director of her new film Movie 43 by performing the unusual stunt in front of him.

Peter Farrelly revealed the boob bombshell during an Ask Me Anything session on Reddit earlier today, where he was grilled about which star has surprised him the most on set.

"I would have to say Halle Berry," Peter explained. "I was a little nervous about meeting her because her scene is so outrageous and I was afraid she might get on the set and balk. Not only did she not, but she thought the scene was too soft, and asked us to amp it up a little. We ended up coming up with a couple of things for her to do that weren't scripted, but were insane. To give you an example [her scene] is about a couple [her and Stephen Merchant] who play Truth or Dare on a first date. Among other things she ended up sticking her bare breast into a bowl of guacamole."

The 46-year-old actress joins a star-studded line-up in Movie 43 which is a series of sketches following three kids' quest to find the most banned film in the world. In her rude and racy scene Halle stars alongside The Office funnyman Stephen Merchant. Peter gushed that rather than be disturbed when Halle exposed her breast into the avocado based dip, he thought it was great.

"She couldn't have been more fun to work with," he exclaimed.
