The superstar looked showstopping in a custom-made flared denim dress from the French fashion house.
She accessorised with head-to-toe Dior accessories, of course – a pink and red Diorama clutch bag and rose-tinted oversized sunglasses.
Topping off the look was her fiery red locks, which had been styled into glamorous, old Hollywood-style side-swept curls.
The Barbados-born singer made history earlier this year by becoming the first black woman to be the official face of Dior.
The singer, who joins a line-up of brand ambassadors including Jennifer Lawrence, Natalie Portman, Charlize Theron, Mila Kunis and Marion Cotillard, said it was an honour to become a Dior ambassador.
“It feels fantastic,” she told MTV News. “It is such a big deal for me, for my culture, for a lot of young girls of any colour. I think, to be acknowledged by Dior is just, it means a lot as a woman to feel beautiful, and elegant, and timeless.”
The Diamonds singer took to Instagram to share some of the images from the campaign, photographed by Steven Klein, which see the star rocking sultry ensembles from a black top with a plunging neckline to a sequinned figure-hugging dress. Her glossy black locks are slicked back and her look is completed with a slick of statement red lipstick for ultimate glamour.
Rihanna also models sunglasses and handbags from the brand’s Esprit Dior collection, unveiled on the catwalk in Tokyo last December.
