Rihanna and Britney Spears preform S&M Remix live at the Billboard Awards. I for one thought this performance was really really awkward. Rihanna does a terrible job with hitting her notes properly and Britney Spears does so much lip-syncing I though I was watching a  Milli Vanilli video.  Now this isn't the first time these ladies have gave really weird performances. Rihanna did a horrible job at the Country Music awards, and don't get me started on Britney Spears Crazy/Lazy Ass. I expected more from them...
