Katy Perry has just weighed in on music’s biggest feud at the moment — calling Taylor Swift a full-on hypocrite for accusing Nicki Minaj of taking down a woman. Perry thinks it’s hysterical Swift told Nicki, “It’s so unlike you to pit women against each other.” The joke, to Katy is that Taylor went for her neck with “Bad Blood” — and proceeded to make a ton of cash off the song that’s all about throwing shade at Katy. In her tweet Perry Wrote, “Finding it ironic to parade the pit women against other women argument about as one unmeasurably capitalizes on the take down of a woman.” Nicki has apparently taken notice and favorited Katy’s tweet, so Taylor may wanna call for backup.
