Reason why Chris Brown and Rihanna got into violent fight

The violent fight between Rihanna and Chris Brown allegedly began after Rihanna discovered a text message from another woman on Chris' phone. Apparently it was a booty call and it made Rihanna livid. She immediately got out of the car on the side of the road and walked off. Some reports have it that Chris called Rihanna to get back in the car and when she didn't he got out and tried to make her get in by force. This began the crazy turn of events that would take place that terrible night.
The backlash for Chris Brown is destroying his career to the point where radio stations are completely pulling his music off the air. As far as Rihanna, she has lost a lot of money cancelling performances due to the terrible turn of events.
