Katy Perry certainly loves her props. So it's no surprise that the pop sensation decided to give this selfie a little pizazz by posing with a tiny crab. While the caption ("Sometimes I can get a little crabby.") is a tad unoriginal, we're willing to cut Katy a little slack. After all, she did just release a chart topping album, Prism, and a number one hit, "Roar".
