Rihanna headed to NYC after her weekend appearance at the American Music Awards, where she wore an outrageous onstage outfit. She's touring the world to support her album Rated R, and she was at a Best Buy last night to autograph copies and even pose for photos with a few lucky fans. This morning was an early one for Rihanna, as she headed out to appear on Good Morning America. She first did a run-through in her black coat, before stripping down to her embellished white blazer to perform and chat with Robin Roberts — check out the video after the jump.
