Lizzie Grubman is very embarrassed that she forgot to put on her dress over her slip:
Lizzie Grubman is also embarrassed that she backed an SUV into a crowd of people, has overbleached hair, never got braces, has tanned and starved herself into looking like old pal Tara "Implants of Granite" Reid, and has become so desperate for fame, redemption, and recognition that she hired a bunch of pretty girls so that MTV would agree to make a show about the "exciting" world of ass-kissing -- er, "public relations."
But that's embarassment on a more long-term, cosmic level. Right then, in that photographed moment, she was just kind of humiliated about the dress thing.
