So Katy Perry and Taylor Swift have been feuding for a while now because Katy stole one of Taylor's back-up dancers (no, not K-Fed) and Taylor wrote “Bad Blood” about Katy. Well, while we were all trying to keep up with our Super Bowl drinking games and Missy Elliot, Katy Perry stepped up her game. Those high-waisted, polka dot, bikinis her back-up dancers wore were basically the same as the bathing suit Taylor wore during her three-week, summer fling with Connor Kennedy. Well done Katy – seriously she used her career defining performance at the biggest venue ever to subtly (or not so subtly) call out her nemesis. Your move Taylor.
