So turns out I have been WAY over thinking this. I need to catch up though. I don't follow many things in the popular media. But I absolutely watch the Grammy's. It is like the superbowl of pop culture. :) My observation was a strong reaction to Rhianna's performance with Drake. Check out the video:
What I see here is an extreme focus on her private area by the placing of a gem dead center in her lower body. I am surprised by her dance moves coupled with her outfit and just how much that is the focus of her performance. The power of the visual focus is strong enough that despite everything else going on, from fire in the background to the dancers and the singing, my focus lands directly on the single gem in her outfit. Basically, Rhianna's girly parts performed at the Grammy's... I wonder if she knew.
