Rihanna speaks on the Chris Brown issue!!

Ryan Seacrest on his hit radio show on KIIS FM called Rihanna to explain her choice to record two duets with the man who brutalized her three years ago.
She said that; "I reached out to him about doing 'Birthday Cake' because that's the only person that really -- it made sense to do the record. Just as a musician -- despite everything else -- that was going to be the person. I thought about rappers, and I've done that so many times, and the hottest R&B artist out right now is Chris Brown. So I wanted him on the track."

If it's not personal, why does she keep going in on Karreuche??
