What in the bloody world was that? it doesn't even look like a mask, it looks like a shark toy she took from a 3-year old kid at the airport and clips it on a rubber band alongside her hoody. She tries so hard, even harder than Mrs. Brand. And it's just not funny/pleasing anymore.
I doubt that Ke$ha knows of this, honestly. And she just tied the plush shark to her head to hide from the paparazzi. Gaga's approach was obviously a different one. So no offense, but your comparison is wack and falls flat.
Okay she is in no way coping Katy Perry. 2nd, I have a feeling she is just wearing it to support sharks or something. I know she loves/cares about animals a lot.
