If you like Katy's music, chances are you'll like Britney's. They're pretty interchangeable in that regard. I can picture Katy singing a lot of Britney songs and vice versa.
Plus Britney and Katy have worked together and are friendly, so there's no reason for anyone to have a personal dislike for either of the two.
well, for starters, Britney and Katy aren't really rivals. also, I've never seen any past history of the two bases going at each other, so that tends to help build friendly relationships on here.
