Miley Cyrus is fully turnt up in 2013. Not only has she been in the lab working on new music with hip-hoppers like Pharrell, Juicy J, Mac Miller, Tyler, The Creator, but she's also been working on her twerking. Above is a video she posted to her Facebook page today, featuring her wearing some sort of unicorn costume while twerking hard to J Dash and Flo Rida's collabo "WOP." Show them how it's done, Miley!
