Gigi Hadid is on the move following her announcement that she and Cody Simpson are going their separate ways [1]. On Sunday, the supermodel went for a hike, which was just one day after her rep shared the breakup news. Gigi was joined by pal Taylor Swift [2], with whom she stars in the upcoming music video for "Bad Blood." [3] The ladies kept it casual for the afternoon, with Taylor showing off her stems in high-cut running shorts and a black tank top and Gigi covering up in a white t-shirt and black and orange compression pants. It all may have been more about catching up than cardio, though — the duo chatted while exploring trails and park grounds together. Read on to see Gigi and Taylor's sunny day together, then catch up on all of Taylor's headline-grabbing friendships [4].
