I think that might be a piece she's wearing for her new video. They're filming somewhere in California. I HOPE it's a piece, because that hair looks like it might be housing small woodland creatures. I mean, I know she walks around with her crazy beehive hairdo. We saw her clean up a Jamba Juice she spilled in a Duane Reade, and she was sporting a significantly smaller bump of hair on her head as well as a purple toothbrush sticking out of her pocket for some reason.
