There's a whole lotta drama happening at Chris Brown's Los Angeles home right now and Ray J is right in the thick of things ... and filming it -- because that's what he does best!

Earlier today we reported that Ray J, who is basically famous because he had sex with Kim Kardashian on camera, attempted to leave Chris' house as things were imploding, but was stopped by cops at the end of the driveway, handcuffed and then eventually let go.

Soon after the incident, Ray J posted a video, defending Brown but being cagey about what was going on.

In the video he says, "I am real upset about today. I am not happy with how things are handled and how people can take a false story and blow it up to what it way more than what it should be."

Along with the video, Ray J wrote, "Thingz gotta change man! This ain't kool! - much support to @chrisbrownofficial and the whole team! #StayPositive #DontLetTheDevilWin."

This morning we reported that Chris was being investigated after a woman claimed he threatened her with a gun at a house party on Tuesday morning. Chris was with Ray J and a couple other pals, at the music man's crib when some "uninvited" guests showed up, including the woman making the claims. The unidentified woman has alleged CB pointed a weapon at her, while other sources claim Breezy was asleep the whole time this was going down.

Apparently the "Turn Up The Music" singer is not answering the door for authorities -- which seems like it's not going to end well. Whatever happens -- it sounds like something went down, cause what's going down right now is all sorts of not good!
