She's performing acoustic version so we'll be lucky with Top 5 unless her boobs drop out or comes dressed up as grandma and does some crazy thing on stage.
Its impossible for her to get #1 with that ****** airplay,I thought that was pretty clear by now,Rihanna is too strong.To get #1 Katy would have to sell like 300k,ain't happening.
another #1 is comming!
