Taylor Swift's Worlds Collide in Calvin Harris's Video Starring Gigi Hadid

Gigi Hadid and her perfect hair star in the new music video for Calvin Harris's song "How Deep Is Your Love." Gigi, of course, is part of Taylor Swift's fashionable squad, and in late June, Taylor and Calvin had a double date with Gigi and Joe Jonas — aka "G.I. Joe." The group also spent time together at Taylor's Fourth of July party, just a week after Gigi showed off her bikini body on the set of Calvin's music video. Watch the music video above, then check out Gigi's music video style plus Taylor and Calvin's cutest moments.
