Life After Break up: Kristen Stewart 'living on Red Bull and cigarettes'

Kristen Stewart's health is allegedly deteriorating in the wake of her split from boyfriend Robert Pattinson. The couple's four-year relationship ended after her brief affair with Snow White and the Huntsman director Rupert Sanders was publicly revealed.

Sources said to be close to the actress, who is currently staying with a friend after moving out of her and Pattinson's Los Angeles home, told Showbiz Spy that she is living on a diet of Red Bull and cigarettes and refuses to eat. "Kristen is a nervous wreck and existing on a diet of cigarettes, sugar-free Red Bull and the occasional bag of potato chips," the insider revealed. "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." Stewart recently failed to appear at a premiere for her movie On The Road.
