Rihanna: Chris Brown Collaboration is Really 'Nobody's Business'

Chris Brown leaves the Supperclub after a night out with pals on Tuesday (January 15) in Los Angeles.

The 23-year-old singer’s rumored on-again girlfriend Rihanna recently covered Complex magazine, and discussed collaborating with her ex on the song “Nobody’s Business”.

“It’s nobody’s business,” RiRi said when asked why she chose to do a song with Chris. “It’s a fun record that The-Dream wrote, and we loved the lyrics. You’re still asking me questions about it, so clearly you don’t know,” Rihanna added when further prodded about it.
