A Timeline of Taylor Swift and Katy Perry's Feud, From Beginning to End

This is where things really heated up: six months into Swift's tour, the three aforementioned dancers were asked to join Perry again for her Prismatic World Tour. They all agreed and left the "Red" Tour in the middle of its run. In an interview with The Examiner, which hit the web in December 2013, Lockhart spoke about this decision like it was no big deal: "It was a great experience and [Taylor]'s a great person to work with, but then Katy contacted us. Obviously we were with Katy for two and a half years, she's like family to us, so we were, like, 'Absolutely.' We weren't really dancing in Taylor's tour anyway so I had got a little bored and I really wanted to do a promo tour.'"
