The Mean Girls actress reportedly flew into a rage at the G-Star runway show on Tuesday night (15Sep09) when she realised where organisers had seated her.
Onlookers allege she began pulling out cards reserving places for other guests, including Juliette Lewis and Taylor Momsen, and throwing them to the floor.
A source tells New York Post gossip column PageSix, "She arrived with her sister, Ali, and two other guests. She had already copped an attitude by refusing to pose for photos, and she had to be dragged into the press line.
"Lindsay decided she wasn't happy with the seating arrangements. She began taking the seating cards for celebrities like Juliette Lewis and Christian Siriano and moving them or throwing them on the floor."
