Nobodies business sing Rihanna, Chris Brown

Track number ten of Rihanna's imminent album Unapologetic is called Nobodies Business (sic)... and it features Chris Brown.

The bad girl pop star has always been vocal about how no one except her knows the 'real' situation with Brown and how the rest of the world can't presume to understand their feelings for each other.

This song can't make that sentiment any clearer.

As the Diamonds star landed at JFK in New York on Tuesday she leaked some exciting information to her fans via Twitter...including that ex-boyfriend Brown has collaborated on a track.

Brown, 23, was convicted of assaulting Rihanna after the 2008 Grammy Awards and was consequently ordered to complete community service and a domestic violence program.

The pair have been spotted at countless events together lately - most recently at Rihanna's Halloween party in Los Angeles where Brown dressed in Arab robes and carried a rifle.

Both Rihanna and the Look At Me Know singer are remaining tight-lipped about their relationship status but according to reports, they plan to announce they are officially back together once Rihanna's album has dropped on November 19.
