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

Gigi Hadid plays Slay-Z in "Bad Blood." The pair apparently met through fellow model Karlie Kloss sometime around 2014, but Swift and Hadid's friendship is even longer lasting at this point. The duo are often spotted out and about together, and of course, Hadid has been spotted at the Eras Tour, where she's a vocal fan. "I'm a psychopath at a Taylor show," she told E! in March. "I go nuts. I'm not cool at all. I'm like the most embarrassing friend."
