Never mentioning Perry by name, Swift explained to Rolling Stone in September 2014 that a fellow female artist whose intentions she’d always been suspicious of “basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me. And I’m surprisingly non-confrontational—you would not believe how much I hate conflict. So now I have to avoid her. It’s awkward, and I don’t like it.”
While the dancers’ exodus had made their own, smaller headlines beforehand, it was Perry’s tweet—”Watch out for the Regina George in sheep’s clothing”—right after Swift’s RS interview came out that cranked their situation up to full-blown feud mode.
