It looks like the love affair between Kristen Stewart and Chanel's Karl Lagerfeld is stronger than ever, with news that the American actress has lent her theatrical skills to a short film which will air at Chanel's next Metiers d'Arts show on December 1 in Rome. The Karl Lagerfeld-directed short has been conceived as a film within a film, taking a behind-the-scenes look at a fictional biopic of Gabrielle 'Coco' Chanel. Stewart tackles the role of an actress playing the younger Chanel, while Géraldine Chaplin reprises the role of the older Coco, a character she's played in the house's other short films, The Return and Reincarnation.

If you're expecting a proper Chanel biopic - don't hold your breath. Lagerfeld suggested to WWD that Stewart was playing the role of a diva-actress. "She played it really, really mean," he said. "You only see her in tests and she's complaining about everything. She's mean with the director; mean with the producer." Stewart's involvement in the Metiers d'Arts show caps off a lengthy involvement with the French luxury house - to date, she's starred in three of their ad campaigns, regularly sits front row at their shows and famously played roulette alongside a whole host of Chanel favourites at the last couture presentation.

The film was shot at director Luc Besson's studio in Paris and also stars Aussie expat and US Harper's Bazaar executive editor Laura Brown as a journalist. As for the reasoning behind the short, Lagerfeld was unapologetic: "They make so many movies about Chanel, why can't I make one?" he said. Good point, Karl.
