Taylor Swift Premieres ‘Bad Blood’ Music Video

After nearly two weeks of teasing fans with posters from her “Bad Blood” music video, Taylor Swift debuted the star-filled clip on Sunday.

The superstar premiered the video at the Billboard Music Awards in Las Vegas.

The action-filled video follows what happens when Taylor’s Catastrophe character is double-crossed by Selena Gomez’s Arsyn and then sets out to get revenge.

The “Sin-City”-esque video (also with nods to “Kill Bill” and “Tron”) includes appearances by Mariska Hargitay and Ellen Pompeo (whose primetime characters inspired Taylor’s cats’ monikers), Selena Gomez, Karlie Kloss, Cindy Crawford, Ellie Goulding, Hayley Williams, Kendrick Lamar, Serayah, Cara Delevingne, Jessica Alba, Martha Hunt, Hailee Steinfeld, Lena Dunham, Gigi Hadid, Zendaya and Lily Aldridge.

The video was directed by Joseph Kahn and produced by Taylor.
