How long is Katy Perry's arm???
Adam Rifkin stashed this in @katyperry
Also, why is Katy Perry wearing blue nail polish on her right hand and red nail polish on her left hand?
also, why are people stupid to think this is actually katy perrys left arm reaching around both selena gomez and kristen stewart?
Aww, we were just joking. You can tell it's not the same arm pretty easily. :)
