Rihanna has said her musical collaboration with Chris Brown "made sense" and is "innocent".
The rapper appears on a remix of her song Birthday Cake, and she features on a version of his tune Turn up the Music.
Their musical union is noteworthy after Chris pleaded guilty to attacking his former girlfriend three years ago and is still on probation for the assault.
Rihanna says it was her idea for her ex boyfriend to appear on her song because he's "the hottest R&B artist" right now.
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 US broadcaster Ryan Seacrest on his radio show.
