Speaking previously about the incident on The Graham Norton Show, Jennifer said: "Oh my God, they were so good for butt itching.
"One rock that I was butt scratching on ended up coming loose, and it was a giant boulder and it rolled down this giant mountain and almost killed our sound guy. His whole station got destroyed. It was this huge, dramatic deal.
"All the Hawaiians were like, 'Oh my God, it's the curse!' And I was sitting in the corner like, 'Haha! I'm your curse! I wedged it loose with my ass!'"
Meanwhile, Jennifer also admitted she refused to do any stunts after completing work on 'The Hunger Games'.
The 26-year-old actress had had enough of getting physical on screen following the four-movie dystopian saga, so when it came to her latest movie Passengers, she left the bulk of the action to her co-star Chris Pratt.
She explained: "As soon as I wrapped Hunger Games I was done with stunts."
