Kristen Stewart will play COCO CHANEL in an upcoming short film.

The movie will feature the actress as the label's founder and will be directed by Karl Lagerfeld, the creative director for Chanel.

It tells the story of a fictional, behind-the-scenes look at preparations for a biopic about Gabrielle 'Coco' Chanel.

Karl's short movie will be shown at the French fashion house's next Métiers d'Arts show, which will take place in Rome on December 2.

Speaking to WWD, Karl said about Kristen: ''She played it really, really mean. You only see her in tests and she's complaining about everything. She's mean with the director; mean with the producer.''

When asked why he decided to make a movie about Chanel, he said: ''They make so many movies about Chanel, why can't I make one?''

Kristen recently revealed there are many perks to being Lagerfeld's inspiration, including being allowed to ''chop'' up designer gowns.

She told the September issue of Nylon magazine: ''He lets me chop dresses, he lets me steal a belt from that dress and wrap it around another ... I'm really into the performance aspect of it, but I still have to make it my own. I don't want to feel like I'm wearing a costume.''
