From the Los Angeles Times:
,,Brown and Rihanna, whose full name is Robyn Rihanna Fenty, were apparently in a car together and got into an argument on North June Street, according to a Los Angeles Police Department statement. Brown stopped the car, the two got out, and the argument escalated, according to police. A witness called 911, but Brown was gone when officers arrived at the scene. The woman suffered visible injuries and identified Brown as her attacker, according to police."
What's funny about this is the magazine covers that followed these statements, they all claim that Riri and Chris's relationship may be in crisis... Imagine that, boy beats you and you think about ending things with him...
Though the two never actually admitted to being a couple, not that it makes any difference...
