If y'all lose respect for Katy over this, then you need to lose respect for every Pop Act in the last 20 years. Katy is far from the only person who has ever been "inspired by" "copied" or anything else. Some of you are just pressed and will do or say anything for the drama.
I mean how would you feel if you've been a fan of a tv series of a man with a blue shirt with an S on it and red shorts that can fly and see through walls and you've swore the creator is a talented genius; only to find out there was an old comic book and it was called Superman. Your opinions should change.
