According to sources and a Los Angeles Police Department report, at about 12:30 a.m. Sunday, Brown and a woman got into an argument in a rented Lamborghini after the pair left the pre-Grammy gala at the Beverly Hilton. Brown stopped the car in upscale Los Angeles neighborhood Hancock Park, the two got out, and the argument escalated.A witness called 911 and a woman with visible injuries identified Chris Brown as her attacker. Brown had already left the scene by the time authorities arrived.
Fox and Fame Images are the only one I can find who say Rihanna is the "unidentified woman". Which is noteworthy because she looked fine last night, about 18 hours after the incident, so maybe it wasn't her. Here's a really tight shot of her face, and I can't see any bruises. Although searching for a black eye on Rihanna really just sounds like the set up to a racist joke, doesn’t it?
UPDATE - okay so I'm a dolt. it was like 5 in the morning when i put these up, and i was sleepy, but it would seem these are from Saturday night, NOT Sunday, therefore before the incident.
