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

Lena Dunham plays Lucky Fiori in the video. Their friendship goes back to 2012 when Dunham tweeted about how much she loved "Red," and Swift responded with how much she loves "Girls," per Vulture. Dunham slid into Swift's DMs, and their friendship was born.

At the time of "Bad Blood"'s release, Dunham was in a relationship with Swift's frequent collaborator Jack Antonoff, and though the pair split in 2018, Swift and Dunham have stayed friends post-breakup. In 2021, Swift was a bridesmaid at Dunham's wedding. And, of course, Dunham has also been spotted at the Eras Tour.
