Appearing the same day Miley's MTV documentary (The Movement) airs, Rihanna's video for "Pour It Up" features plenty of twerking: strippers on poles, their booties bouncing in the water. Even by Rihanna herself, as she sits atop a golden throne. Are these two things connected? We'd like to think this is Rihanna's way of schooling Miley in some actual twerking — while also wearing perhaps the shortest jorts the world has ever known. Beat that, Cyrus.
