Kelce, wearing a top hat and tails, joined Swift for a skit where he carried her to a sofa. The appearance delighted fans, with videos and livestreams showing loud screams from the audience. Swifties were excited by Kelce's cameo, with one fan noting it as a hard launch for their relationship. Speculation arose on social media that Kelce's surprise appearance was pre-planned, given his custom-made costume. Kelce's support for Swift, attending multiple tour concerts and showing up at Chiefs games, has been evident. This London performance also saw Swift changing lyrics in her songs to reference Kelce, showcasing their relationship publicly.
