When leaving a nightclub in London on Sunday Rihanna was approached by a pissed off stranger who began to scream at her because of her relationship with Chris Brown. The unindentified man then decided to throw a British energy drink at Rihanna. She fell against the metal shop grate and cut her knee. In the mist of the action Rihanna's bodyguard also injured his leg and had to be taken to the hospital and treated. Luckily, this choatic situation didn't harm Rihanna anymore then she already was.
