Source claims: “Kristen Stewart is a nervous wreck”

A report has claimed that Kristen Stewart is a mess at the moment.

According to the source, the Twilight actress is struggling since the news broke about her affair with Rupert Sanders.

“Kristen is a nervous wreck and existing on a diet of cigarettes, sugar-free Red Bull and the occasional bag of potato chips,” revealed an insider, reports Showbizspy.

“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.”

“Kristen is grief-stricken and has hit rock-bottom. In many ways, Kristen living off cigs and Red Bull is a way of punishing herself.”
