Anne Hathaway's spot outbreak during Les Miserables diet

Actress Anne Hathaway hated the tough diet regime she embarked on to lose weight for her role in upcoming movie musical Les Miserables, because it made her break out in spots.

The Devil Wears Prada star plays doomed prostitute Fantine in the film adaptation of the hit stage musical, which is set in 19th Century France.

Hathaway, who also chopped off her long locks for the part, cut out treats from her diet to lose weight for her scenes - but she experienced an annoying side effect of her eating overhaul.

During filming, she told women's magazine Allure, "I'm doing some crazy weight stuff right now... 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 being all like 'And I got a pimple', Yeah."
