Rihanna changes hairstyle faster than you can say UMBRELLA. In fact, when I hear her name, I get confused as to which hairstyle I should picture her in because she's had so many in just a span of 3 years or so. Some celebrities are comfortable with their brown, long, wavy hair until they reach a certain age. In fact, we can say that most actresses make sure that they stick to the hairstyle that they had when they became famous. Not Rihanna, though. Perhaps she wants to be famous for CHANGING hairstyles, among other things?
