@Trina, Mary hasn't exactly been copying Rihanna's hairstyles because she has had this hairstyle before Rihanna came out, however, she is looking quite much like her, as well as Keri. Both Mary and Beyonce have a problem with trying a new look, they are too afraid. Unlike Rihanna, never sticks with the same ole' more than 4 months, which despite her musical talent, she is quite a leading trendsetter.
