The Hunger Games actress went on to star with Bradley Cooper in Silver Linings Playbook after the franchise's first instalment came out last year.
When asked if winning an Oscar for Silver Linings Playbook means she has become more of a diva, she replied that she is more bossy on The Hunger Games: Catching Fire's set.
Laughing, she told the November issue of Empire magazine: "Well, of course I changed. I told them, 'Things are going to be a little different around here from now on'."
Lawrence plays Katniss Everdeen in the Hunger Games movies, and although the story is far removed from her American upbringing, she said that she identifies with the character in some ways.

"But there is the connection in that she doesn't feel like just part of the town anymore. Now everyone treats her as a celebrity... Whereas she still feels like she's part of them."
Lawrence went on to say that, since appearing on the big screen, she hates that people treat her like she is an alien or superior being.
"I get that a lot," she admitted. "I'll go to get a coffee where I always get coffee and all of a sudden there's this weird mood, and I'm like, 'Come on, I still get coffee here, just say hello'."
