It's no secret that Taylor Swift's a big fan of Kendrick Lamar, and vice vera, so it's nice to see they'll finally be teaming up together.

Lamar is set to feature in Swift's forthcoming video for 1989 'Bad Blood', alongside a bunch of Swift's famous friends (Lily Aldridge, Hayley Williams, Ellie Goulding, Lena Dunham, etc).

Lamar will play a character called Welvin Da Great while Swift plays Catastrophe; the video will premiere on May 17th during the Billboard Music Awards, and you can check out the poster (yes, it even has a proper poster) above.
