I have said it before and I will say it again. Rihanna needs rehab. Yesterday was a prime example of why she needs it. For four hours she left a group of 2500 kids waiting for her appearance. Four hours. In those four hours, someone called to say she would be late twice. First she was supposed to be a few minutes late and then two hours late. She was four hours late to a performance that she had given away as part of a contest to a school that made her the best video. When she finally arrived, she spent a grand total of 16 minutes at the school and said she was sorry for being late. That was it. She blamed traffic. Uh huh. What she should blame is the fact that she is pretty much useless everyday after all night partying until about 3 or 4 in the afternoon. This is when she wakes up. I think the only time she is not actually partying is when she is on stage or teaching a certain B- list comedic actor about the art of pegging. Well, she is probably wasted then too.
