The much awaited 20/20 Rihanna interview with Diane Sawyer aired on ABC last night.Rihanna revealed that how her relationship with chris Brown turned into obsessive and dangerous.

It all came crashing down in Feb 2009, when Brown punched Rihanna in a car after a text message was recived from his ex-girl friend.

Rihanna admitted, “Even if Chris never hit me again, who is to say that their boyfriend won’t? Who’s to say that they won’t kill these girls? These are young girls, and I just didn’t realize how much of an impact I have on these girls’ lives until that happened. It was a wake-up call.”
