The award winning star opted for a demure look as she attended a dinner celebrating the launch of her Jewellery line with Chopard in Cannes on Thursday night.
Rihanna, 29, looked stunning and exuded old-school Hollywood glamour in a black tulle gown by Ralph & Russo as she arrived at the star-studded event.
She shared the photos and wrote:
” Thank you to the wonderful Caroline Scheufele for such an unbelievable opportunity to create high-end jewellery for the first time in my career! Had a blast tonight at the official launch event for our collaboration!!! RiRi ❤ @chopard #RihannaLovesChopard “
