WATCH: Taylor Swift shares video for 'Bad Blood'

After quite a bit of build-up - as well as, it seems, a bit of a re-jug in the studio - last night saw Taylor Swift shared the video for her new single, 'Bad Blood'.
A re-working of the album track sees Kendrick Lamar dropping some bars on an altogether deeper, more bass-driven track than appeared on 1989, while K-Dot is joined in the neo-noir video by the likes of Selena Gomez, Lena Dunham, Jessica Alba, Cindy Crawford and Paramore's Hayley Williams.
It's good to have friends to call on, we guess.
Featuring explosions, fistfights, samurai swords and sports cars, there's a whole lot going on; check out the amazing video below...
