Katy Perry. She should be put in a glass box and dress up like a paperdoll everyday. That would be her only good use. Singing, decent, but it's all about melting your popsicle and if you think that 'kissing a girl and liking it' wouldn't be a number one-no matter who's singing it-with the Hollywood look-then you are mistaken.
'You change your mind like a girl changes clothes...?'WTF?! It's wwaaayyyy to bubblegum puke for me.
