The critically-hailed drama earned Lawrence her first Oscar nomination. Yet the flannel-and-jeans part didn't sum up all Lawrence had to offer onscreen. So she glammed up some for an Esquire magazine photo shoot and was soon cast as Raven/Mystique in "X-Men: First Class," requiring layers of blue paint to be applied to her body each shooting day.
"I have no modesty left," Lawrence said. "I was either standing or sitting on a bicycle seat while seven women painted me everywhere and it was horrible. But I can't wait to go back."
To fans of "The Hunger Games," Lawrence is the indomitable, emotionally torn Katniss Everdeen, the heroine of what will be a movie trilogy. Yet after being cast in the role, she almost turned it down "because of the size of it" and because of what she said she watched happen to the actors starring in another incredibly popular trilogy.
"With the poor 'Twilight' actors, they had no idea what they were getting themselves into," Lawrence said. "I was afraid of my life changing. I had a wonderful life and I had this imaginary made-up future of myself where I would be a soccer mom driving a minivan and raise a normal family, like what I grew up in, and I couldn't see that future if I said yes to these movies."
Lawrence said it took her three days to decide to agree to do "The Hunger Games."
"It was difficult," she said "But I've never once regretted saying yes to 'The Hunger Games,' which is odd, 'cause I expected to."
A $400 million, blow-out-the-doors, smash hit, "The Hunger Games'" success reshaped, not just Lawrence's life, but the life of her loved ones, especially her mother.
"God bless her," Lawrence said. "She texts me almost every single night, 'Are you home? Are you OK?'"
But Lawrence has yet to been spotted staggering home from a Hollywood nightclub.
"No, you'll never see that, because I don't like it," she said. "I just don't like clubs and I don't have the stomach for getting really wasted. Four drinks, I'm barfing. I don't know what it is. My brothers are really ashamed of me."
Following her break-up with actor Nicolas Hoult, Lawrence has experienced paparazzi scrutiny, but it was a tabloid tale about a costume party outfit that really made her mad.
"The tabloid that said that I dressed up as a medieval, like a sexy medieval something and that upset me more than the dating rumors that have been circling around that were fake," she said. "If somebody thinks I'm going to dress sexy to a costume party, they have another thing coming."
When she does venture out to a soiree, Lawrence said Hollywood royalty still leaves her slack-jawed.
"I saw Meryl Streep at a party one time and somebody was about to introduce me to Bill Maher," she said. "And so he was reaching his hand and I literally put my hand in his face and looked at Meryl Streep and go, 'NOT NOW, BILL,' and I just stared at her all night, and followed her around and drank and stared at her like a creep."
But as Oscar night approaches, Lawrence's fellow nominees seem to be looking up to her, something she finds humbling. She said seeing the ascendance of actresses younger than herself, such as Quvenzhane Wallis from "Beasts of the Southern Wild," is amazing.
"It's really fun," Lawrence said. "And then there is also a sense of relief because it's like, 'Oh God, there's going to be another-- I'm not going to be relevant forever.'"
