Lawrence was posing for photos alongside two of her co-stars when she had a "mini meltdown" and began yelling at the loud photographers.
A 30-second clip of the moment finds the young actress all smiles as photographers can be heard in the background asking each other to move so they can get a shot, but after about 20 seconds Lawrence loses it and begins screaming herself.
In an interview with David Letterman, the Silver Linings Playbook star explained she wasn't feeling well that night and that she even had to go to a doctor to be examined for a possible ulcer. She added that doctors were unable to determine what was causing the intense pain.
