Taylor Swift [1], Gigi Hadid, and Martha Hunt are inseparable! On Saturday, Taylor had the support of her pals at her 1989 concert in Detroit. As the singer belted out her hit "Style," the ladies made their way over to her on stage. Taylor shared a picture of their big moment on Twitter [2], writing, "When two of your best friends strut the runway with you during 'Style.'" Still feeling the energy after stepping off stage, Gigi took to Instagram with her reaction [3]. "Will never forget this moment. T, you are amazing. Detroit, you are amazing. Thank you for sharing tonight with me!!!!!" Just one day before, the trio re-created their memorable scene from Taylor's "Bad Blood" music video [4].
