Rihanna, Chris Brown Tracks 'Not Intended To Shock'
A pal of RiRi's claims their collaborations show they have moved on...
He explained: "At the end of the day, she's my friend, so whatever she wants to do is whatever she wants to do.
"She's pretty smart too. The same questions that went through my mind, and I'm an artist also, had to have gone through hers,
"When she raised the question to me, I know she's not crazy. So my thought was you've been thinking about this, you've already thought it out, so evidently you know what reaction you gonna get."
