To coincide with Chanel's Métiers d'art 2015/2016 show, taking place in Rome on Tuesday evening, the French house finally released its much-hyped short film entitled "Once and Forever," directed by Karl Lagerfeld and starring his celebrity muse Kristen Stewart. The 11-minute clip, which also features Geraldine Chaplin, Jamie Bochert, Amanda Harlech and Baptiste Giabiconi, is set behind the scenes of a Coco Chanel biopic, with Stewart portraying a punky, foul-mouthed young actress (aka herself?) who's been cast to play the designer in her early years — and who's a bit of a diva about the film's direction. She sings, dances, speaks French and generally channels the legendary fashion designer in a way we've never seen before, with plenty of modern attitude. Which, we're guessing, is precisely why Lagerfeld likes her so much. Watch it in full above.
