Katy Perry has changed her look over the years according to her taste. In all of them, she has looked absolutely stunning. Of course, a lot of effort goes into preparing herself for the public eye, or at least for professional photographers who can’t wait to get an ugly picture of her.

However, tabloids got a hold of it and it remains in circulation to this day.
