In a music video that appears to have about 120 cameos, Taylor Swift’s ‘Bad Blood’ adds actresses Jessica Alba and Serayah to an already star-studded cast including Hailee Steinfeld, Lena Dunham, Karlie Kloss and Lily Aldridge. Jessica Alba plays Domino with Serayah as Dilemma. Seeing all the promotion, this video looks like it is going to be pretty epic.
