According to TMZ, Brown explained that the incident all started when RiRi was going through his text messages and found something she wasn’t too keen on. Things allegedly escalated quickly, with his recollection being that “she tried to kick me, but then I really hit her, with a closed fist, I punched her.” It gets worse from there: “I busted her lip. When I saw it, I was in shock. I was like, ‘F**k, why the hell did I hit her? From there she just spit in my face … spit blood in my face and it enraged me even more.”

Brown says the incident is going to haunt him forever. You can check out a video clip from the documentary where he discusses the incident in more detail below.
