This just gets worse and worse. Rihanna — who is fully cooperating with authorities — said Chris choked her until she lost consciouness, while threatening to kill her.

They began squabbling after leaving Clive Davis’ pre-Grammy party late Saturday. Shortly after midnight, things blew up. Brown pulled his silver Lamborghini to the side of a street in L.A.’s Hancock Park neighborhood. That’s when, per the source, Rihanna grabbed the car keys and tossed them out the window, sending Brown into a rage.

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.

After being treated for her injuries, police escorted her down a rear elevator and into a waiting Mercedes, the source says.

I’m hearing from sources that the fight after Clive Davis’s party had to do with one of them flirting and dancing with other people — but the sources disagree about whether that person was Chris or Rihanna. I have one source that says that a girl Chris had been seeing on the side was at the party, and that got Rihanna upset, and I have another that says that Rihanna was dancing with other guys at the party, and that got Chris upset. Perhaps it was both.

Either way, choking a person until they pass out is never an appropriate resolution.

Why do I hate Mandy Moore so much?

Oh, I don’t know.

Maybe because when her fashion line, Mblem, shut its doors this week, this was her statement:

“I love the fashion world. I’m fascinated by it. I’m humbled by it. If I were to dip my toe back in there, it would have to be the right situation… a great partnership that could represent a true reflection of me and my ideas and, you know, that wasn’t happening. So next go round, that needs to be top of the list.”

It’s the way she talks.

It’s so douche-y. So holier-than-thou. I dunno. Everything about her annoys me so much.

So, ya know, I’m happy that her clothing line is over, but annoyed to hear that she’s working on a new album of a California ’70s-inspired pop.

I hope it fails!

Despite earlier reports that Rihanna was not cooperating with authorities, it looks like she is cooperating fully. So, ya know, good for her.

Meanwhile, T.I. went on Carson Daly’s show last night and was asked about the incident. “I spoke to him today,” T.I. said. “He’s 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.’”

Ummmm … what the fuck, T.I.?

I don’t care what actually happened, someone should have told you that you do NOT GO on national television acting like domestic violence allegations are the kind of thing you can be “a little concerned” or “cool” about. You, my friend, are headed to jail in March — isn’t that right? So maybe you don’t have this whole life thing figured out just yet, and maybe you should shut the fuck up.

I’m just so annoyed with all this.

The Huffington Post has an interesting piece today on Octomom Nadya Suleman — apparently she’s had plastic surgery, and it seems like the surgery was intended to make her look more like Angelina:

Both women are 33 and are mothers to arguably, at least for now, the two most famous broods in the world. They also survived divorce, longed for children and chose to become single parents.

Consider this: In photos of Suleman pre-octuplets out Monday, she looks noticeably different. She has had what appears to be lip implants or filler injections to pump up her pucker. She’s also evidently had a nose job. Both nose and lips now mimic the features of Jolie, as others have pointed out … Suleman already had brown eyes and has now grown her dark brown hair all the way down her back.

But beyond the physical, Suleman chose Ann Curry to break her media silence. Curry has long been Jolie’s go-to girl and has flown around the world for multiple interviews with the movie star, including to Cannes and to Namibia while Jolie was pregnant with Shiloh … Curry flew to California for the octuplet scoop.

I’d thought it was just a coincidence that this chick looked like Angelina … I didn’t realize she’d had surgery to look that way!

VERY VERY creepy!!!!

Thanks Anna!

“Britney has a beautiful soul. We share something really special. The truth about us will come out eventually, but it’s not for me to talk about. I love her…I still love Britney.  I’m her boyfriend.”

Adnan Ghalib, in a Heat magazine interview, in which he insists that he and Britney are still in a relationship despite the restraining order she has filed against him.

Holy shit.  Yeah, I get that pot is illegal, but does anyone thing that this has just escalated to an unreal level?  Even the governor of South Carolina thinks it’s meaningless.

Eight people were arrested this week in connection with the Michael Phelps bong incident-seven with possession and one with distribution.  Police confiscated the bong that some its owner tried to sell on Ebay for $100,000.

Phelps has not been charged yet, even though he’s the one person in the photograph who is actually taking a hit.  Stay tuned.  Beet, get the bail money ready.
