69178Gigi Hadid is going to be in Calvin Harris' new music video! The model was spotted on the set of his new vid, "How Deep Is Your Love," in Malibu. Knowing that she's BFF with Taylor Swift, it's kind of cool that Gigi is working on projects with her bestie's boyfriend. While the "Shake It Off" singer was nowhere to be seen, it would be pretty awesome if she made a cameo. After all, the model starred in the pop star's video for "Bad Blood." We would love to see an on-screen reunion!
