Taylor Swift has unveiled her star-studded and action-packed new music video at the Billboard Music Awards.
The pop star, who leads the awards with 14 nominations, screened the stylised video for Bad Blood at the beginning of the ceremony in Las Vegas.
The all-action video stars Lena Dunham, Mariska Hargitay, Ellen Pompeo and Jessica Alba, as well as musicians like Kendrick Lamar, Ellie Goulding and Hayley Williams of Paramore, among others.
Swift has been building up the video's release for weeks, releasing a series of Sin City-style posters on Instagram featuring everyone who stars in the video.
