Rihanna was one of the first major music stars to hit the VMA red carpet in LA today. She showed off a new look, modelling a short and sleek pixie cut paired with her sexy white gown. She's opening the show with her latest single, "Cockiness (I Love It)" and will be joined on stage by A$AP Rocky. They're among a talented group of artists selected to perform during the show which also includes Alicia Keys, Pink, and One Direction. Rihanna's up for five awards tonight and will face off against best friend Katy Perry and Drake, Goyte, and M.I.A. for video of the year. The celebration is just getting started so stay tuned for more photos from the red carpet!
