Kristen Stewart 'Once and Forever': Watch The 'Twilight' Star's New Chanel Short Film By Karl Lagerfeld [WATCH]

Kristen Stewart stars as a young Coco Chanel in 'Once And Forever,' a new Chanel short film directed by Karl Lagerfeld himself.

After seeing behind-the-scenes images and the trailer of Once And Forever, fans can finally watch Kristen take on the role of Coco Chanel in the fictional biopic.

The 11-minute movie showcases Stewart’s character, and she clashes with the director, played by Jeremie Elkaim. At one point she tells a producer, “You want to make a commercial? Go hire another f*cking actress.” The film premiered in Rome on Tuesday, where Chanel’s new Metiers d’Art collection was unveiled.

Kristen stars alongside Geraldine Chaplin, who reprises her role as a middle-aged Coco Chanel in the film. Karl directed the biopic, which was shot in two days at Luc Besson‘s Paris studio in July 2015.

The project was first teased last month, with Lagerfeld telling Women’s Wear Daily that he developed the short film with Stewart, one of his muses, in mind to star. “I think she’s one of the greatest actors of her generation,” said the designer, noting he was “very flattered and honored” when Stewart agreed to participate.

In a behind-the-scenes video, Chaplin also gushes about Stewart’s performance.

Kristen brought her impeccable acting skills to set and shows off a mean streak that fans are not used to seeing from the 'Twilight' star. From mild and sweet to totally hot-tempered, watching Kristen can totally take anyone to an emotional rollercoaster.

Aside from her acting, Kristen made headlines earlier this year when she broached the topic of her sexuality in an interview with Nylon magazine after rumors of a relationship with visual effects producer Alicia Cargile surfaced.

“Google me, I’m not hiding,” she told the magazine at the time. “I think in three or four years, there are going to be a whole lot more people who don’t think it's necessary to figure out if you’re gay or straight. It’s like, just do your thing."
