Rihanna Attacked By Crazed Fan!

Just weeks before Rihanna is to kick off her Diamonds World Tour in Buffalo, New York, she had a scary encounter with a crazed fan which resulted in RihRih cutting her leg, and sending her security guard to the hospital!

While in London, a fan reportedly threw a bottle at the singer and was heard screaming something or another about Chris Brown. The incident caused her to stumble and cut her leg on a metal grate, and her body guard injured his knee while chasing the perpetrator and was taken to the hospital for treatment. Unfortunately, the mad man is still on the loose....
