Featuring Taylor Squad members such as Selena Gomez, Karlie Kloss, Lena Dunham, Zendaya, Kendrick Lamar and many more, the video centered on Swift --sorry, "Catastrophe" -- battling her enemies (or rather, her real-life friends posing as enemies).

The biggest surprise of the video is that not only did Kendrick Lamar appear, but he rapped two different verses during the tune.
