People Editorial Guidelines Updated on November 13, 2023 02:32PM EST Travis Kelce was spotted enjoying plenty of sweet moments during Taylor Swift's Eras tour show — but one in particular saw him looking very surprised! Kelce, 34, had a moment of shock during the night after the singer, 33, referred to him in a lyric change to her song “Karma” in her concert at Buenos Aires’ Estadio River Plate in Argentina on Saturday. The NFL player's reaction was caught on film as he watched Swift perform during the Latin leg of the Eras Tour, after flying in from the U.S. on Friday. In footage posted by a concertgoer, Kelce stood next to the singer's dad, Scott Kingsley Swift, in the VIP tent as Swift sang her track, "Karma." The pop star then switched up the lyrics to the song, singing, “Karma is the guy on the Chiefs coming straight home to me,” causing Kelce to flash a big grin. The "Blank Space" singer's dad also reacted with excitement, tapping the NFL player on the shoulder and clapping in support. Kelce attended Swift's Argentina show on Saturday night.

In another clip posted by a fan taken moments later, Swift appeared to look fondly towards Kelce from the stage as he blew her a kiss and waved at her at the end of the song. She later returned the gesture more directly when she ran backstage into the arms of Kelce — who was waiting to greet her after the show — and planted a kiss on him. Swift referred to Kelce as she changed the lyrics to "Karma" during the show.
