O snap! Word just hit the Grammy Red Carpet and media sources around it that Chris Brown is being investigated for felony battery.

There was an “incident” around 12:30a this morning with a female who was in his limo after they left the Clive Davis Pre-Grammy party. Apparently he and an unnamed female–who everyone’s speculating is his girlfriend pop star Rihanna–got into a heated argument in the limo and it escalated. She ended up having very visible injuries to her body and she has just filed charges.

While Chris was definitely with Rihanna at the party, the female’s name who filed the charges against Chris is being held in secret right now. Apparently that’s the policy for felony battery issues. Cops involved in the case just said: “Any victim who’s involved in a domestic violence incident is entitled to confidentiality.” And since they’re calling this a “domestic violence” charge, this leads folks to believe this could very well involve Rihanna. Damn. Ish just got real in Tinsletown.

Interestingly, when Rihanna’s reps were asked about her well being, their response was: “Rihanna is well. Thank you for concern and support.” Very suspicious to say the least.

Chris is set to perform tonight, but the head of the Grammys just announced during the pre-show he doesn’t think Mr. Breezy will be hitting the stage. Or Rihanna either. It’s rumored they’ve been replaced by Boyz II Men. Drama!

UPDATE (7:21pm EST): It has just been confirmed that neither Rihanna nor Chris Brown will be performing or showing up at all to tonight’s Grammys. Grammy staffers are saying Chris may be replaced by Justin Timberlake. Chris has NOT been arrested as of yet. But LAPD Officer April Harding has just said: “If police locate Brown, yes, he’s subject to arrest.”

UPDATE (7:50p EST): The Recording Academy’s official statement: “We have just been informed that Rihanna will not be attending tonight’s 51st Annual GRAMMY Awards. We’re sorry she is unable to join us this evening.’ No confirmation from the Academy about Chris Brown, but the Grammy staff confirmed earlier he will not be attending. Being considered to replace him are Justin Timberlake and Al Green.

STORY DEVELOPING…

Yeah Rihanna will bounce back, Chris Brown not so much.

His career is gone "Forever eva eva, and eva eva eva"

^ I think you're thinking of Christian Bale?

Grammy day was supposed to be a glittery affair for R&B's reigning It couple, Chris Brown and Rihanna. But things went horribly amiss.

About the time Brown was scheduled to be singing "Forever" onstage at Los Angeles' Staples Center, he was instead detained by police, being questioned for allegedly roughing up Rihanna.

Brown, 19, turned himself in at the LAPD's Wilshire station around 6:30 p.m. and was booked on suspicion of making criminal threats, a charge that carries a maximum penalty of four years. The case will now be sent to the district attorney's office and further charges could be filed. He was released from jail after posting $50,000 bail.

"He was very professional and didn't appear to have injuries," said Sgt. Bridget Pickett, adding, "he's a good looking young man."

While Brown appeared unscathed, sources tell E! News that the alleged victim was Rihanna, 20, and that she suffered visible bruises on her face during an early morning confrontation. Both in turn balked at scheduled Grammy appearances.

A spokeswoman for Brown's label declined comment and calls to his attorney, Mark Geragos, weren't immediately returned.

Meanwhile, Rihanna's publicist, Amanda Silverman, said the "Disturbia" singer "is well. Thank you for concern and support."

Per department policy, police declined to identify the alleged victim in the incident, which occurred about 12:30 a.m. in the Hancock Park area, apparently as the two were heading home from Clive Davis' annual pre-Grammy bash, where they had been all smiles.

In a statement, police say Brown and his companion "became involved in an argument. After stopping his car, Brown and the woman got out and the argument escalated. The woman suffered visible injuries and identified Brown as her attacker."

By the time officers arrived on the scene, Brown had split.

Rihanna, whose full name is Robyn Rihanna Fenty, decided against singing a medley of "Disturbia" and "Live Your Life" at tonight's awards. Likewise, Brown scrapped his scheduled performance of "Forever."

"We're sorry she is unable to join us this evening," said the Recording Academy. A virtually identical statement was issued for Brown's absence.

Brown and Rihanna were up for dueling Pop Collaboration With Vocals awards, Brown for his duet with Jordin Sparks on "No Air," Rihanna with Maroon 5 for "If I Never See Your Face Again." Brown was also contending for Male R&B Vocal Performance for "Take You Down." Neither Brown nor Rihanna won anything.

After the ceremony, Recording Academy President Neal Portnoy told E! News that he first learned of the situation "pretty late in the afternoon," about three hours before showtime.

"Musicians are no different than anybody else. I'm not judging. I'm sorriest that they weren't there for their moments on stage," he said, adding that he's never had to deal with replacing two segments at the last minute.

"I'm hoping that [the awards are] the story and should not be ecliped by this part of business," Portnoy said. "I think the story is...the music that went on stage."

Backstage, Anthony Hamilton, winner of the Traditional R&B Vocal Grammy with Al Green, said his pal was pressed into emergency service "about an hour and a half before the preshow."

Green crooned "Let's Stay Together" with assists from Justin Timberlake and Keith Urban.

Asked if old-pro Green really was able to take the stage on such short notice, Hamilton suggested the R&B icon was practicing last night.

Said Hamilton, "He knew something could happen."

What a f*cking animal.
I saw a note posted on facebook and nearly went ape shit.

Apparently he was pissed out of his mind because Rihanna gave him herpes.

...we'll have to wait to see if this is true.

Im going to make a voice blog about this sometime on snapvine.
I feel like verbally bitching.
