Taylor Swift pulls all the stops in her epic music video for “Bad Blood.” The short film, directed by Joseph Kahn, opened the 2015 Billboard Music Awards on Sunday, and features an A-list cast including Swift’s girlfriends Selena Gomez, Jessica Alba, Lena Dunham, Ellie Goulding, and Hayley Williams, who play badass femme fatales.

Kendrick Lamar also holds it down as Welvin Da Great and rides shogun with Swift’s character Catastrophe. Not only does he grace the screen, he contributes some vicious bars on the remix.

“I don’t hate you, but I hate you / Critique, overrate you / These beats of a dark heart are basslines to replace you,” he raps.
