Rihanna and Chris Browns' Nobodies Business, which appears on Rhi-Rhi's new studio album Unapologetic, has leaked online. News of the controversial collaboration was first announced after Rihanna uploaded an image of the track-listing for the album earlier this week.

The website HipHop-n-More.com is streaming snippets of the new record while 'Nobodies Business' has also turned up on YouTube. The up-tempo track sees the former couple sharing vocal duties. "Your love is perfection. Just point me in the right direction. I'm a give you all my affection. Whatever we touch becomes infectious," sings Rihanna. The lyrics will certainly leave some of the Bajan star's fans uneasy and on the chorus she sings, "I'm a be your girl. I wanna make you mine and it ain't nobodies business," which kind of speaks for itself. Brown - who was convicted of brutally assaulting Rihanna - sings, "Me and you, ain't nobody's business, no it ain't nobody's business", 

The track follows on from their collaborative remixes Birthday Cake and Turn Up The Music, which were unveiled earlier this year. Rihanna's new album Unapologetic - also featuring collaborations with David Guetta, Eminem and Emeli Sande - is released on November 19, 2012.
