The blood just went from bad to worse. Taylor Swift’s new video for her single “Bad Blood,” all but officially confirmed to be about her riff with Katy Perry, is stacked with Swift pals both old (Lena Dunham, Karlie Kloss) and new (Ellen Pompeo!). Perry’s no loner herself: her all A-list entourage includes everyone from Miley Cyrus to Rihanna to O.G. pop star Madonna. As we’ve learned from Step Ups one through five, there is only one way to settle this feud once and for all: dance battle!
Catch the premiere of Swift’s “Bad Blood” music video during the Billboard Music Awards on Sunday, May 17 at 8 PM EST/PST on CTV.
