Anne Hathaway chopped her hair for the upcoming Les Miserables role

Anne Hathaway has admitted to cutting her daily food intake down to only 500 calories for her role in the forthcoming movie Les Miserables but she has also agreed to cut her hair.

Anne Hathaway, 29, who usually flaunts a thick mane of long brunette locks has trimmed her hair to barely one inch in length, in order to achieve the look of her character in Les Miserables.

The actress was pictured leaving London’s The Box nightclub in the early hours of Sunday morning with the newly cropped do.

Anne Hathaway looked especially gaunt as she left the venue with fiancé Adam Shulman and their friends.

As they hopped into a taxi she tried to conceal her fresh crop from onlookers who took a while to catch on to her identity.

Grabbing her head as she made her way home, Anne Hathaway is evidently still getting used to her short style.

Wearing a dark coat and blue jeans, as expected she appeared noticeably slimmer than usual as she has embarked on a hardcore diet for her part in the film.

Anne Hathaway plays Fantine, a struggling factory worker who is forced into prostitution to provide for her illegitimate child and ends up selling her hair for financial gain.

A film source told the Daily Mirror: “Anne is playing a destitute factory worker-come-lady of the night.

“Unfortunately, she only has 15 to 20 days to lose as much weight as possible – up to a stone-and-a-half – because she’s been filming the scenes showing her fit and healthy, almost slightly chubby.

“It’s not ideal but, as with any high-budget movie, there are strict time constraints.”

Anne Hathaway looked a far cry from the glamorous situations fans are used to seeing her in but the dramatic decision was all for the greater good.

While many stars opt to don a hairpiece to save their precious tresses, Anne Hathaway was clearly determined to be as authentic as possible for the musical motion picture.
