Beneath her sometimes hard exterior Rihanna certainly had a soft spot for her Grandmother. Over the weekend, Rihanna’s Gran Gran Dolly lost her battle to cancer, this devastating news happened right before Rihanna’s performance for the Peace and Love festival in Sweden. As expected, Rihanna took the loss pretty hard but proceeded to perform apparently intoxicated. Fans of the ” You Da One” singer went ham on twitter saying she shouldn’t have performed and that the show was a mess. However, Chris Brown took to twitter to express his condolences : Keep your head up Ri-Ri!
