Grumpy Cat has become very famous. She just shot a Friskies commercial and created more noise at SXSWi than Al Gore. In order to hide from her millions of crying fans and the paparazzi, she has a few costumes to conceal her identity. They range from Joaquin Pheonix to Nicki Minaj. Below is a video of the photo shoot with Grumpy Cat looking ultra pissed off.
