Fresh off her adorably neurotic chit chat with David Letterman, actress Jennifer Lawrence, who dealt with a three-week stomach ache and exhaustion from the whirlwind of promoting 'The Hunger Games: Catching Fire,' hit 'Good Morning America' (Nov. 21) for a breakfast chat with Robin Roberts. J. Law once again displayed her neurotic cuteness.

Roberts compared Lawrence to her 'Hunger Games' character Katniss Everdeen, calling them reluctant victors and heroines, to which J. Law joked the stakes are lower in her life.

"Most of my friends are still trying to figure out what they want to do," she said in reference to her superstardom. "I feel so lucky. I'm doing what I love and I can do that forever. Whatever comes along with it is just part of it."

J. Law joked that despite her reputation, she is not the prankster on set since she is not creative enough to come up with anything elaborate, chalking up her "pranks" to being mean.

As for the pixie chop aka her new hairdo, which looks fab on her -- it was just an impulse move. Lucky for her, it turned out well. That's not always the case with impulse haircuts.

J. Law is, and will remain, America's No. 1 Girl Crush.
