We smell a new Rihanna fragrance brewing! Yesterday afternoon, Rihanna posted the picture above with the caption "Guess what we doing?" We're not exactly stretching here in assuming that the "Pour It Up" singer is in the initial stages of producing a new fragrance. Her last launch, Rogue, hit stories last month to join her other scents Rebelle, Nude, Reb'l Fleur. So what do you think? Are you ready for the next RiRi fragrance venture?
