(Pics/Video) Drake and Rihanna go x-rated on stage as the rapper buries his head in her crotch

After causing a frenzy by kissing on stage in Maimi,it appears Rihanna and Drake went a little more x-rated .

A fan's video shows the rapper and singer, seductively singing Work to each other before Drake shamelessly buries his head in her crotch. Rather than pushing him off like she usually does, Rihanna put her hands around his head and flashes a smile at the crowd.
