Kristen Stewart has found herself in the midst of a scandal after it was revealed she was cheating on her long-time beau, Robert Pattinson, with director Rupert Sanders. Apparently, Stewart hasn't been dealing with the drama well and is on a very destructive diet.
"Kristen is a nervous wreck and existing on a diet of cigarettes, sugar-free Red Bull and the occasional bag of potato chips," a source said. "She's been hiding out at the LA home of a producer friend and is looking pale and worn-out. Whenever anyone tries to push her to eat even a small bowl of soup, she either claims that she's just had something, which isn't true, or that she's nauseous and there's no chance of keeping anything down."
The source added that Kristen's unhealthy diet "is a way of punishing herself."
