Can you put a list?

Miss Hudson.

E.T and Teenage Dream alone >> anything my miss Clarkson

sorry but that would be unfair because one of the option will run out of "hits"


jk jk

Katy Perry, duh. Honestly, only Rihanna can compete with Katy when it comes to legendary hit singles.

Queen Katy has the better and bigger hits!

Katy of course

This.

I'm a big fan of both, but I go with Katy.

Is this thread even serious??
