chris brown punched rihanna?

WTF.  Multiple sources have reported that R&B superstar Chris Brown surrendered to police last night and was charged with a felony after he allegedly struck an unidentified woman during a fight early Sunday morning, but now Fox News is saying that woman was his girlfriend, Rihanna.  Both Brown and Rihanna were set to perform at the Grammys last night but both pulled out.  Brown has posted a 50,000 bail and is now free.  Fox says…

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.
