I think the only pictures we've ever posted of Rihanna were from the red carpet and God knows she wasn't dressed like this. Now, I'm not the biggest Rihanna fan (well, of her music anyway), but clearly being at a Rihanna concert is not only about the music. From looking at these pictures there appears to be a great deal of squatting involved. Squatting and latex. Oh and asses, yes, lots of asses.
