Chanel released a photo and a video teaser for Cara Delevingne and Pharrell Williams's campaign for Chanel Metiers d'Art on Monday, Ace Showbiz reported. 

Delevingne tweeted about the campaign, showing off a picture of herself and the "Happy" singer dressed as a royal princess and a royal prince.

Chanel also released their own teaser for the campaign by posting a teaser video for "Reincarnation," a seven-minute short film starring Delevingne and Williams.

"Reincarnation" was created and directed by Karl Lagerfeld, Chanel's head designer and creative director, and will feature a new song by Williams and Delevigne titled "CC the World." The short film will be released on Dec. 1 on Chanel's official website and in Salzburg.

The film follows the story of Gabriel "Coco" Chanel, played by actress Geraldine Chaplin, and the creation of the Chanel jacket after Chanel was inspired by a hotel's elevator operator, according to The Independent.

Williams will portray the reincarnated Emperor Franz Joseph I of Austria, while Delevigne will play his wife Empress Elisabeth "Sisi" of Austria.

Lagerfeld talked about his short film during an interview in Paris saying "Reincarnation" has a touch of pop art, according to WWD.

"It's not meant to be a historical reconstruction or something heavy like that," he said. "This is light and funny."

Lagerfeld also revealed that it was Williams who picked out Delevingne to work with and complimented the singer, saying Williams "was easy to work with, very pleasant, very professional."

Delevigne, who had expressed a desire to be a singer, said that upon finding out Williams was writing a duet for them thought she "screamed down the phone at him."

The set was created in Paris at Luc Besson's studio with a cast of more than 60 extras, Delevingne, Williams, and former model Adnan Taletovich, who will play a night porter, model Brad Kroenig and his son Hudson, who plays a bellboy, and more. Also present during the filming were Lady Amanda Harlech, model Baptiste Giabiconi and model Heidi Mount, and Lagerfeld's communications director Caroline Lebra, according to WWD.
