Can someone explain to me what exactly happened with Chris Brown?

[Holy Smokes =)]

I see it all over Twitter and on Tumblr... apparently Chris tweeted something and/or got into an argument, and he even deleted his twitter... I'm confused.
But that was four years ago. He did it recently?!?!

He beat up his girlfriend and now everyone hates him, or they should anyway.

[Nothing In Return]

probably infested with another std from Rhianna

He didn't get the message that SWAG means to turn one into a douche bag.

Apparently he got into it with this comedian name Jenny. Calling him a women beater which of course he gets aggravated by it. Honestly It was childish of him to get into it with her cause its affecting himself and career. That's why he's probably doing drugs no (no offence.) Im a fan but I'm dissapointed in him. Honestly, when he's with Rihanna it's like he's always getting into some kind of Trouble. When he was with Karreuche Tran he as doing good. Smh. He needs to get it together. I'm sorry but i though it was overall childish that he was calling her and paying her attention. It wasn't worth it at all.
