Chris Brown Explains How He Beat The Crap Out Of Rihanna [VIDEO]

There wasn't a lot of doubt that Chris Brown gave Rihanna a vicious beating in 2009.

We've all seen the photos, and Brown ended up pleading guilty to using his hands on his girl.

In the new documentary Chris Brown: Welcome To My Life, Brown explains that his relationship with Rihanna took a bad turn after he came clean about having sex with a woman who once worked for him, which RiRi hadn't known about.

'She hated me. After that, I tried everything. She didn't care, she just didn't trust me after that," Brown said.

On the car ride home, Rihanna saw that the woman had texted Brown earlier. She became enraged and then things got violent.

"I hit her with a closed fist, I punched her. I busted her lip and when I saw it I was in shock, like ‘Fuck!" Brown explained. "Why the hell did I hit her like that?’ So, from there she just spit in my face and it enraged me even more. it’s a real-on fight in the car. We’re driving in the street. I’m like ‘Yo, we’re trippin’. What the fuck? Like, what are we doing?’ She’s trying to grab for my phone to throw it out the window. So, she grabs my nuts, when she [did] that, I bit her arm. Because I was still trying to drive. It was a petty stupid fight.
