RiRi Shows Her Ass - Again

I get the feeling that if RiRi was a boy she's give a whole new meaning to the term "rock out with your cock out". LoL. No, seriously though....did I miss the memo or are body suits and fish nets the new attire of pop stars? Either way, she did look fantastic performing at the Hammerstein Ballroom in NYC last night.
