Gigi Hadid walked the red carpet at the American Music Awards in LA on Sunday night and appeared to show her loyalty to BFF Taylor Swift when she came face to face with Harry Styles. While One Direction was talking to E!'s Giuliana Rancic, the supermodel came over to playfully interrupt their interview. She was quick to give Harry a cold handshake to say hello, which didn't seem out of place until she then warmly embraced his other bandmates, Niall, Louis, and Liam. Harry, who famously dated Taylor in 2012, also appeared to roll his eyes after Gigi walked over and said hello. Watch the awkward encounter above and a closer look at Harry's reaction below, then check out Harry basically admitting that One Direction's "Perfect" is about Taylor.
