The 24-year-old Oscar winner has been on a whirlwind press tour for the Mockingjay: Part 1, and is currently in NYC making the media rounds.
She was running late for her appearance on The Late Show With David Letterman, so J. Law rushed inside once she arrived to the studio, prompting fans who waiting outside to begin booing her.
Perhaps Jen noticed the jeers and felt bad, because after she finished taping her appearance, she took time on her way out to sign autographs.
But eager fans basically bumrushed the actress and nearly knocked down the barricade, causing J. Law to make a beeline for her waiting SUV and security to spring into action.
So you boo the girl for not stopping, but then when she does stop, you make her feel unsafe? Not cool.
