Sunday's Billboard Music Awards opened with the much-hyped, blockbuster-like premiere of Taylor Swift's video for "Bad Blood," which featured new verses from co-star Kendrick Lamar.

Among the clip's cameos are Jessica Alba, Lena Dunham, Hayley Williams, Ellie Goulding, Mariska Hargitay, Ellen Pompeo, Cara Delevigne, Cindy Crawford, Selena Gomez and more.

The Joseph Kahn-directed music video can be seen below.
