It isn't even out on the news stands and already its one of the most talked about images of the sultry songstress Rihanna. It is quite easy to see why. With not a stitch of fabric on her except a few gold trinkets, her ever growing collection of skin arts, and strategically positioned poses, Rihanna's provocative nude photo s by famed nude photographer Mario Sorrenti (who is also the contributor to this year's PIRELLI Calendar) grace the pages of GQ Magazine's December 2012 Issue. As an end-of-the-year roundup, the upcoming issue names actor Channing Tatum as Movie Star of the Year 2012 and Ben Affleck as Filmmaker of the Year 2012. And Rihanna? She took home the title as the Obsession of the Year 2012.
