Rihanna is ready to explain herself.

The world was shocked in February when the singer, 24, tapped abusive ex-boyfriend (and current secret lover) Chris Brown to sing on a sexually explicit remix of her song "Birthday Cake" -- and she, in turn, crooned on a remix of his own song "Turn Up the Music."

Rihanna addressed concerns over the collaboration chatting with Ryan Seacrest on his radio show Thursday.

"I reached out to him about doing 'Birthday Cake' because [he was] the only person that really made sense to do the record -- just as a musician. Despite everything else, that was gonna be the person."

Brown, 22, violently assaulted then-girlfriend Rihanna in February 2009; as Us Weekly has reported, the pair have been secretly hooking up for a year despite his ongoing relationship with girlfriend Karrueche Tran.

"You know, I thought about rappers, [but] the hottest R&B artist out right now is Chris Brown. So I wanted him on the track," she explained matter-of-factly.

In turn, she agreed to guest on his own remix. "It was a tradeoff," she said. "We did two records -- one for my fans, one for his fans. That way, our fans could come together. There shouldn't be a divide. It's music and it's innocent."
