The "Rude Boy" hitmaker will star in the label's upcoming Secret Garden campaign, a spokesperson for the French luxury label confirmed to WWD.
The campaign, entitled "Secret Service", has been shot by photographer Steven Klein at the Palace of Versailles and will be released in both print and on film.
The spokesperson said, "Film and print versions of the campaign are scheduled to run this spring."
The advert will be the fourth video released by the brand as part of their Secret Garden campaign.
The three previous installments have all featured models, including Daria Strokus, Melissa Stasiuk and Xiao Wen Ju, walking through the palace's decorative gardens, situated on the outskirts of Paris.
The short films were previously captured by Inez van Lamsweerde and Vinoodh Matadin, with the hugely popular third video, which depicted models sashaying though the French chateau's grounds, racking up over nine million views on the official Dior YouTube channel.
The 27-year-old singer joins a host of other A- list beauties in fronting the label, including actresses Jennifer Lawrence, Marion Cotillard and Natalie Portman.
She has also previously fronted campaigns for Balmain and is the creative director of sports brand Puma.
