When Rihanna and Chris Brown decided to get back together for a pair of remixes— RiRi's "Birthday Cake" and CB's "Turn Up The Music"— the reaction from fans and critics alike was mixed. "How could she collaborate with someone who she so famously had a public and violent falling out with?" many wondered. 

But Rihanna defended herself this morning on Ryan Seacrest's radio show.

"I reached out to [Brown] about doing 'Birthday Cake' because that's the only person that, really, it made sense to do the record," she said. "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 and then in turn he was like, 'Why don't you do the remix to my track?' and it was a trade-off."

Rihanna said it was a way for their fan bases to link back up.

"We did two records— one for my fans, one for his fans— and that way our fans can come together," she said. "There shouldn't be a divide, you know? It's music and it's innocent."
