Rihanna and Taylor was involved in a pretty nasty social media war last week which first started when the G.O.O.D music artist and friend of Chris Brown's, put out a video of herself singing, then the 'Diamonds' singer uploaded a video of her hair stylist singing the same song. Though the feud may have died down for a bit, seems as if Taylor is back at it after she followed up with her very own twerk video shortly after Rihanna released the official music video for 'Pour It Up.'
