It looks like Chris Brown and Rihanna were having an argument right after the Clive Davis pre-Grammy party. When, Rihanna took his Lambo keys and threw them out of the window. When she did, and he couldn’t find the keys, Brown lost it. According to E! News, the rest went down like this:

He tried in vain to find the keys, then came back to the car, put his hands around her neck and, according to the insider, said, “I’m going to kill you!”

According to the source, the 20-year-old “Disturbia” singer told police that she lost consciousness, and when she awoke, Brown had fled.

According to the source, her right eye was blackened and badly swollen and she had hand prints on her arms. The responding officers were so concerned about her, they drove Rihanna to the hospital in their squad car instead of waiting for an ambulance.

Officers took two sets of photographs of the banged-up singer, one at the scene and the second after she was admitted to Cedars-Sinai Medical Center for treatment. Those photos were presumably among the evidence presented to the district attorney.

Kanye West talks about Rihanna and Chris Brown (to E! News’ Ryan Seacrest):

“She has the potential to be the greatest artist of all time and, in that sense, I feel like that’s my baby sis and I would do any and everything to help her in any situation. I don’t want to speak more into the specifics with that situation, but all I’ll say is it’s just so devastating. I feel like, just as a person, I don’t care how famous she is or even if she just worked at McDonald’s, that should never happen. It should never come to that place.”

T.I. had a different take on it from his “space,” which is that of the offender:

“He’s [Chris is] cool, you know. He’s a little concerned about the situation, but he’s still the same Chris. I told him, ‘This too shall pass.’ “We’re celebrities, we’re entertainers, but we’re still human—all of us. Don’t expect us not to make mistakes, because we will.”

Chris Brown talks about living in an abusive relationship:

“He made me terrified all the time, terrified like I had to pee on myself. I remember one night he made her nose bleed. I was crying and thinking, ‘I’m just gonna go crazy on him one day…’ I hate him to this day.”

His step father talked to Access Hollywood and fired back and Chris Breezy!

“[Chris] has to take responsibility for his own actions.” When asked he thought Chris beat up Rhianna, he said “I wouldn’t be surprised.”
