Rihanna's 'Unapologetic' tracklist reveals 'Nobodies Business' collaboration with Chris Brown

Yes, that Chris Brown. Rihanna and he partnered up on Track 10 which, appropriately, is called "Nobodies Business." The reportedly on-again couple previously collaborated back in February on two tracks: "Birthday Cake" and "Turn Up the Music." We'll be interested to see if "Nobodies Business" discusses Rihanna and Brown's relationship once "Unapologetic" comes out Nov. 19.

"To the world, I feel like there's no closure," Rihanna told Vogue of the continued focus on her relationship with her abusive ex. "There's some obsession that's continued even throughout when we weren't friends or couldn't be friends at all. Hated each other. The world hasn't let go. They haven't seen any progress in our friendship, because they don't see anything, really, besides the song."
