Chris Brown & Rihanna

So how do you explain not remembering the little dispute you had with your girlfriend -- the dispute that made you a felon?

If you're Chris Brown, you explain it by saying that Larry King badgered you into amnesia.

Brown is reacting to a clip that was released in which he said he didn't remember beating Rihanna.

Here's his statement:

"There have been reports on the Internet that I didn't remember what happened that night with Rihanna. I want to try and set things straight.

That 30 seconds of the interview they used of me was taken from a one hour interview during which that same question was asked something like 4 or 5 times -- and when you look at the entire interview you will see it is not representative of what I said.

The first four times – or how ever many times it was - I gave the same answer -- which was that I didn't think it was appropriate for me to talk about what happened that night. I said it was not right for me and it really wasn't fair to Rihanna. The fifth time – or whatever it was – I just misspoke. I was asked, "Do you remember doing it?" and I said, "No."

Of course I remember what happened. Several times during the interview, my mother said that I came to her right afterwards and told her everything. But it was and still is a blur. And yes, I still can't believe it happened because it is not me or who I am or is what happened like anything I have ever done before.

As I have said several times previously, I am ashamed of and sorry for what happened that night and I wish I could relive that moment and change things, but I can't. I take full responsibility for my actions. What I have to do now is to prove to the world that this was an isolated incident and that is not who I am and I intend to do so by my behavior now and in the future."

With his mom and his lawyer, Mark Geragos, by his side, Brown did a pre-taped interview for King's upcoming Wednesday show -- and told Larry that he's still "in shock" about the beating. He also says he's still in love with Rihanna.

Need a refresher -- here's the brutal blow-by-blow.

The twist: Drake was widely rumored to be Rihanna's first rebound guy ... even though he claimed they were just "good friends."

Law enforcement sources have now gotten specific with us... police took pictures of Rihanna's injuries and they are "horrific."

As we reported, the photos show major contusions on both sides of the singer's face -- there is serious swelling and bruising. Her lip is split and her nose bloody. We have now confirmed there are bite marks on one of her arms and on several fingers.

And we now know this... Rihanna claims Brown struck her with his fists and that's what did the damage. There was no object used in the alleged attack.

Rihanna refused treatment at the scene, but before she left cops took photos. We're told the photos alone are "devastating proof of abuse."

And we've learned it was not Rihanna who called 911. Someone in the area heard her screams and called.

One of the law enforcement people put it this way -- the contusions "look like an MMA fighter or something ... [It] looked like she was growing devil's horns."

We've also heard that Rihanna may have suffered bite wounds on one of her legs and arms, however, one source close to the situation tells us he doubts that is the case.

Chris Brown has been booked on a felony criminal threats charge. If the D.A. files the case, domestic violence charges could be added.

TMZ can confirm that Chris Brown just entered an LAPD station, where he turned himself in to police.

Chris is being investigated by the LAPD for an alleged domestic violence felony battery that occurred early this morning near Hancock Park in L.A. Police officials said earlier today they may arrest Brown when they find him. Well, now they know where he is.

According to the female victim -- who cops refuse to identify -- she and Chris got into an argument which turned violent. Cops say when they arrived at the scene, Brown had split, but the woman had "visible injuries and identified Brown as her attacker."

Brown and his girlfriend Rihanna were together earlier last night, attending Clive Davis' pre-Grammy party -- and both canceled their scheduled performances at tonight's event.

Law enforcement sources tell TMZ Chris Brown is being investigated by the LAPD in an alleged assault on a female.

According to police, Brown and a woman whom cops refuse to identify were arguing inside a vehicle around 12:30 this morning when suddenly things allegedly turned violent.

Cops say they received a 911 call, and when they arrived they noticed the woman had visible injuries. We're told she then identified Brown as her attacker. Cops say Brown had left the scene by the time police arrived.

Cops say they are looking to speak with Brown and may arrest him when they find him.

When we called reps for Brown's girlfriend, Rihanna, for a statement, her people told us, "Rihanna is well. Thank you for your concern and support."

UPDATE: Grammy officials have just announced that Rihanna will neither perform on the show tonight -- as scheduled -- nor walk the red carpet for the event. The same announcement has been made about Chris.

The singer and his boo Rihanna got real close in Ocean City, Maryland this weekend. And the by way things look -- she let him know who the real pop star is.

They had a not-so-subtle night out, causing a major scene with fans, cops and bodyguards when leaving a NY tattoo parlor -- and were spotted hitting a bar together after that. Seriously guys, give it up already.
