We Need to Revisit the "Bad Blood" Music Video and Its Supersize Cast

Swift is a well-documented "Grey's Anatomy" fan; she even named one of her cats after its main character, Meredith! So that's why she asked star Ellen Pompeo to play Luna in the video. Pompeo told Jimmy Kimmel in 2016, "Her people called my people and said, 'Would you like to be in this video?' And I was like, 'Of course, that would be so fun. There's an old lady section? I'm down,'" per Entertainment Weekly. Pompeo attended the Eras Tour in March of this year.
