The actress landed her first film role in the teen movie opposite Lindsay Lohan and Rachel McAdams, but she was unprepared for her first walk down the red carpet and still cringes over her see-through dress.
She tells Britain's Glamour magazine, "For the Mean Girls premiere, I wore this really beautiful Moschino dress that I bought with my own money. It was small polka-dots on black, and beneath it I wore a white bra, black thong. Idiot! It all showed. I felt really bad. It was my first premiere and I didn't have any money for a stylist or hair and make-up. I have learned a lot since then, though."
