So far, “Diamonds” and “Stay” off of Unapologetic, have been a major success for Rihanna, while “Pour It Up” is slowly working its way up the charts as well (and FINALLY getting a video…). Now Rih has announced what will be the fourth single off of the project, revealing the artwork for the David Guetta-produced “Right Now.” What other tracks off the album would you like Rihanna to make a single?
