If we are talking about record sales Beyonce Alicia, Mariah, Ciara And Ashanti have all sold more than Rihanna in a week. Rihanna just went platium the other da which means she sold a million plus. Beyonce, Alicia Ashanti Ciara and Mariah have gone double or triple platium with there first and second albums. Rihanna had sooo much promtion for good girl gane bad and still haven't gone double platium and she is far from it. Rihanna has never had a # 1 album all the other ladies that i mention before has had at least 2. Face it Rihanna has catchy songs and that it she doesnt sell record just singles. Peole just love her look.
