On the set of The Hunger Games: Mockingjay – Part 1, Jennifer Lawrence and her castmates often pulled pranks on each other to keep spirits up. Lawrence revealed that she had once been the target of a particularly disgusting prank that haunted her especially during naptime.

At the Los Angeles premiere of The Hunger Games: Mockingjay – Part 1, which was held at the Nokia Theater LA Live, Lawrence told Entertainment Tonight’s Kevin Frazier about what went down behind the scenes. “We all mess with each other to make sure all of us have a conflicted experience. I got a Tiffany’s box filled with crickets!” Lawrence said.

The trick was apparently spearheaded by Jeffrey Wright, who plays Beetee in the movie. He reportedly gave Lawrence a jewelry box that was full of crickets, which later infested her trailer. “It was the most awful combination of feelings in the world. It was like, Tiffany’s!? Jeffrey! You didn’t have to do that! And then I opened it… it was awful. And they were in my trailer for months, I couldn’t get them out,” continued Lawrence.

The 24-year-old actress also said that she would sometimes hear the crickets when trying to take naps in her trailer. Lawrence’s co-stars reportedly loved the prank.

“That was like the best prank ever pulled on anyone. She’s just fun to mess with,” said Josh Hutcherson, who plays Peeta, the love interest of Lawrence’s character.

Hutcherson added that he thought pranking Lawrence was “fun”. “We just love giving her crap all the time, and whether it’s a prank or just, you know, giving her a hard time, it’s the best,” said the 22-year-old Hutcherson.

The Hunger Games: Mockingjay – Part 1 will be in theaters in the US on November 21. Fans of the highly successful movie franchise, however, will reportedly have to wait another year to see Part 2, which is slated to show on November 20, 2015.
