This is the first solo single by the Barbadian national hero to reach this height.
Her features on "This Is What You Came For" by Calvin Harris and Eminem's "Love The Way You Lie" are the two other singles to hit the billion views club.
"Diamonds" remains one of Rihanna's biggest hits on the Billboard charts, peaking at number 1 in December 2012.
Rihanna is still a far way from the top, as the most-viewed music video in YouTube's history is still Pinkfong's "Baby Shark Dance," which currently sits at more than 11 billion views.
