The news comes after the New York Post's Page Six reported that the couple — both 32 — was spotted having dinner with friends at the Beatrice Inn in New York over the weekend.
The couple has sparked romance rumors since Rih split from her boyfriend of three years, billionaire Hassan Jameel, in January. (Then, The Sun reported that Rihanna and A$AP Rocky had been seeing each other, but a source told E! that she was still single.)
In July, Rihanna featured the "Everyday" rapper in her Fenty Skin campaign. The duo did several interviews together to promote the collaboration.
