List1 of 5
1. Katy Perry and Zooey Deschanel
Perry's new single, aptly titled "Not The End of the World," has Deschanel performing as the singer after being mistaken for Perry by aliens and eventually saving the world after Earth is set to self-destruct. Side note: Seeing Deschanel without her signature bangs is jarring. After watching the actress lip sync in a Katy Perry-esque getup, I totally see the similarities, but you'd think that true fans (alien or not) would be able to differentiate the two.
