Ri-Ri's no stranger to controversy on Twitter. She's done everything from posting provocative pics to fighting fans. This time around the Barbadian pop princess proceeded to take a shot at Chris Brown’s new Vietnamese girlfriend, Karrueche Tran, tweeting an image of a rice cakes package—referring to a subliminal line featured in the “Birthday Cake” remix recorded with both artists. Breezy retaliated by throwing a few shots back at his ex in his "Theraflu" freestyle.
