Rihanna's 'Loud' tour certainly started off with a bang.
While performing the catchy single, "What's My Name?" the sexy songstress took a pretty nasty spill. Dressed in short shorts, a bikini top and stiletto ankle boots, the singer tripped and face planted on stage. However, Rihanna, a professional minx, seamlessly transitioned from clumsy to sultry. We'd expect nothing less.
