Appearing on The Late Show with David Letterman on Tuesday, the actress, who plays heroine Katniss Everdeen in the new teen action film, confessed that she is still awkward when dealing with the fame that has resulted from her lead role in the hit franchise.
"I am a troll. I hate myself. I think the movie is great, but their biggest mistake was [casting] me," Lawrence said of seeing herself on screen.
"Out of the four premieres, I've tripped in two or three of them. Like, massive trips. It's so scary and then I end up getting so nervous that I get really hyper. So then I go do interviews and I'm like, 'I'm like a Chihuahua. I'm shaking. I'm peeing!' And then afterwards I'm like, 'I just talked about peeing on the red carpet!'"
Lawrence recently revealed that she was initially against a Hunger Games movie being made as she feels that most books are ruined in their film adaptations.
The 21-year-old has compared the character of Katniss to a "futuristic Joan of Arc", saying: "She's this hero that doesn't mean to be a hero. She's a symbol of revolt, and freedom, and hope."
