Tonight's Billboard Music Awards opened with a raunchy performance of "S&M" by Rihanna, during which a bunch of random hands tried to caress her vagina. Then Britney Spears shot up from under the stage! Except that it wasn't good, because Spears lip-synced (Rihanna sang live), danced like she had arthritis, and even managed to mess up a song-ending pillow fight.
