The Pop princess, Rihanna, announced yesterday via twitter that her next official single is the Mikky Ekko assisted: Stay. The piano driven ballad, actually allows the singer to display her vocals. And she actually delivers on this one. Rihanna also let be known that the uptempo, club joint: Pour It Up has been sent out to urban radio, I can’t wait to see the video for that…but Def Jam knows that we are all waiting for the Chris Brown assisted track: Nobody’s Business to become a single. I mean if they were bold enough to put the track on the album, don’t be afraid to make it a single!
