Brittany Snow: (about filming "John Tucker Must Die" as she was going through an anorexia problem) Thank goodness for my co-stars, Sophia Bush and Arielle Kebbel. I told them, "You have to look out for me, because this is so hard." We would work out together, and then they would pull me off the treadmill, and Sophia would be like, "Maybe you should eat this." We had slumber parties. I started having fun, which was unheard of. Before, I was like, "I can't have fun. I can't go out and have a burger with my friends. How many calories are in that burger?"
