Rihanna is used to creating controversy, just check out her cover artwork for her new single titled, "Diamonds". The cover photo features Riri holding a paper, filled with diamonds. It pretty much looks like she is rolling a marijuana cigarette, but with diamond instead of green. Rihanna wears marijuana themed clothing AND isn't shy about instagramming photos of herself smoking a hand rolled substance. 'Diamonds' will release worldwide on September 26th.
