I feel sorry for the people there having to see Katy and Rihanna on the same night. This was unbearable to watch: having to see Katy try and sing her generic songs with here weak, shaky vocals. She had to have multiple costume changes, props, glitter, water and bright colours to make up for her lack of talent. It just proves that having no.1 singles has nothing to do with talent, nor how creative or good the song is.
