Rihanna - Russian Roulette [Live At David Letterman] + Interview About 'Rated R'

Princess Bajan Fenty performed "Russian Roulette" on the David Letterman Show. You can check out the performance above. Her album, "Rated R," is rumored to have sold just under 200K behind Susan Boyle, Adam Lambert and Lady GaGa (in that order). Big surprise but these upsets have been plentiful lately, with Mariah and 50 Cent not debuting at the top spot either. Below is a short interview where she talks about the album, she also mentions that "Stupid In Love" or "Photographs" will be the fourth single. I'd much rather have "Rude Boy," "Fire Bomb," "Rockstar 101," or "Cold Case Love" be the fourth single though.
