It won't be long before Luke kills Katy bc she has no value to him besides being a puppet. He keeps Kesha alive because she writes his songs for him while locked in a cage, so she's fine. When Katy starts flopping Luke will kill her for the catalogue sales
Yet this ugly rat DNA'd man has sold 2x the albums, had a longer streak of top 10 hits and 6 times the Grammy awards. Has performances/moments that are known & remembered while Booby pays men to dress up as cartoon sharks to get herself talked about (keep in mind this bitch is 30+).
