I think it will be Beyonce...Her and her Husband are very good in promotion and sure do like to turn every thing to their favour. Remember how they sold out teckets to their concets years ago just by pretending to break up. Even their recent twins, everything they turn to a business.
For those that think its not a good idea to have celebreties here should think again, because tweeter, facebook, instagram etc are trending today is because the top celebrities are using their platform. I think it will be a welcome development seeing the amount of followers they command on every of their social media handle.
