NEW YORK (AP) - People have been scratching their heads over Rihanna's musical collaboration with Chris Brown, but she says it "made sense" and it's "innocent."
    
Brown appears on a remix of her song "Birthday Cake" and she appears on a remix of his "Turn up the Music." Their music union is noteworthy because Brown beat up Rihanna three years ago and is still on probation for the assault.
    
Rihanna says it was her idea for Brown to appear on her song because he's "the hottest R&B artist" right now. He then asked her to be on his song.
    
She says the partnership allowed fans to come together, adding: "There shouldn't be a divide. ... It's music, and it's innocent."
    
She made the comments to Ryan Seacrest on his radio show on KIIS-FM in Los Angeles.

In this article from 2009 on MTV.com,  Rihanna told Good Morning America's Diane Sawyer about her experience with Chris Brown, the night she was attacked by Brown, her then boyfriend.

Rihanna said in part, "The thing men don't realize when they hit a woman, it's the face, the broken arm, the black eye, it's going to heal. That's not the problem. It's the scar inside," she continued. "You flashback. You remember it all the time. It comes back to you, whether you like it or not. And it's painful, so I don't think he understood that. They never do," according to MTV.com.

ABC News in 2011 reported that Chris Brown stormed off the set of Good Morning America after an interview in which he was asked about Rihanna's restraining order against him.
