MORE ON CHRIS BROWN (WHAT A FRIGGIN TOOL) AND RIHANNA

WITNESSES SAY RIHANNA WAS INDEED TREATED AT A HOSPITAL SUNDAY:


Even though the cops aren't saying so, it's pretty apparent by now that RIHANNA is indeed the "unidentified woman" who was assaulted by CHRIS BROWN . . . (--Rihanna's boyfriend, FYI) . . . early Sunday morning.


--A witness at Cedars Sinai Medical Center in Los Angeles tells RadarOnline.com that Rihanna was brought through the ER early Sunday morning.


--The witness was in a room across the hall . . . and was supposedly able to see what was going on because Rihanna's room had a glass door.


--He (or she) said Rihanna was tended to by doctors, and then interviewed by police . . . quote, "Rihanna was clearly very upset by what had happened and I could hear her screaming.


--"Rihanna was trying to get her point across about something, she sounded like she was crying as she tried to get her point across.


--"Her staff was also very shaken by what had happened. Later on I saw one of the assistants crying into the shoulder of the security guard . . . something terrible had clearly happened to Rihanna."

TMZ says Rihanna suffered, quote, "two huge contusions" that swelled up on either side of her forehead . . . and also a bloody lip and nose. One source said she looked like, quote, "an MMA fighter or something".


--There are also reports of BITE MARKS on Rihanna's hands and fingers.


--Another police source told E! Online that when police arrived at the scene, Rihanna wouldn't let anyone touch her, because she was in so much pain.


--Brown turned himself in to police Sunday night at about 6:30 P.M. He was booked on a charge of making criminal threats and released on $50,000 bail. The district attorney's office is currently mulling over whether to hit him with any additional charges.


(--Here's a blast from the past for you: Chris Brown's attorney is Mark Geragos. You may remember him as the attorney for wife-murder Scott Peterson, shoplifter Winona Ryder . . . and the totally-innocent-in-the-eyes-of-the-law Michael Jackson.)
