It seems that Zooey Deschanel is getting a little miffed that instead of being recognized for everything she has done in movies she is instead being mistaken everywhere she goes for Katy Perry. In an interview with MTV, The Zooey says, “It's a little bit annoying, to be totally blunt. The only similarity that we have is that we look a little bit alike.”
It would suck to have worked for years and years trying to be recognized for what you have done and then all of a sudden people are probably running up to her and making really bad kissing a girl jokes.
The good thing about The Zooey though is she is happy for the success of Katy, she just wants her to maybe dye her hair blonde or something. If I were The Zooey I wouldn't worry about it too much. Give it another six months or so and then people will forget all about Katy Perry.
