The fan talked about how Swift reacted to a certain "bad call" during the game. According to the supporter, the way Swift talked about the referee served as proof that she is, indeed, a true Chiefs fan. "She really is just a fan when she's there, which is so cool," the Swiftie revealed in a TikTok video .

Swift, 35, wore a red Charlotte Simone coat ($404) and black Chanel bucket hat with black argyle tights by Sheertex and knee-high Veronica Beard suede boots ($695) for her arrival just ahead of the game on Saturday.
