"Rihanna flipped out, and that's when their happy-go-lucky relationship turned toxic for good. They were constantly fighting from that point on, but remained together for the time being," Shira said.

According to the documentary, despite the troubled relationship, RiRi and Brown attended the 2009 Clive Davis Grammy party together. But things went bad when the girl with whom Brown had sexual relations came and said hi to the singer.

"Rihanna began crying uncontrollably and Chris (who says he had no idea the girl was going to be there, nor did he want her to come up to him) finally calmed her down and the two left in his Lamborghini. The duo was arguing incessantly and Chris swore to her that he wasn't keeping any secrets. He begged her to go through his phone and sure enough, she came across an unopened text from the girl at the party, indeed telling him she would be there. Rihanna flipped out and the two were going back and forth," the writer said.

"It got so intense that he punched her with a closed fist and left her lip bloody—blood that she spit in his face. It didn't stop there. She grabbed his private parts and he bit her arm."

The documentary Chris Brown: Welcome to My Life is released in 450+ select theatres nationwide.
