Taylor Swift's relationship with Travis Kelce caused a seismic shift within the Kansas City Chiefs organization. ESPN's six-part docuseries The Kingdom, which premiered its first two episodes on Thursday, August 14, detailed the early days of the pop star's romance with the Chiefs tight end. Swift, 35, made her first appearance at Kansas City's Arrowhead Stadium in September 2023 when the Chiefs hosted the Chicago Bears. Not only was her attendance a sign that she and Kelce, 35, were the real deal, it also raised plenty of logistical concerns for the Chiefs organization.
