Talk about a starving artist.

Anne Hathaway has revealed the drastic measures she went through to lose weight to fit the part of the tuberculosis-ridden prostitute Fantine in the upcoming film adaption of Les Miserables.

“I’m doing some crazy weight stuff right now,” Anne revealed to Allure magazine, while talking about her crazy 500-calorie a day diet to lose 16lbs in less than three weeks.

“I’m on day six of detox… this diet makes me break out, so I love that. Nothing like living on hummus and radishes and then be all, ‘And I got a pimple. Yeah!’”

The 29-year-old also had to get fit for her role as Catwoman in the third installment of Christopher Nolan‘s Batman series, The Dark Knight Rises, which transformed her into a gym rat, as Anne explained, “The Catwoman suit. It was a psychological terrorist… the suit, thoughts of my suit, changing my life so I would fit into that suit… it dominated my year. I went into the gym for 10 months and didn’t come out.”
