The Kansas City Chiefs tight end had several other sweet moments during Swift's Argentina Eras Tour show on Saturday
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.
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 then put his hands over his head in shock as fans cheered, before raising his arms and bobbing them along to the song.
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.
During the concert, Kelce had showed plenty of support for Swift, and was even filmed holding up a sign that read, “WE WILL STAY,” as she sang her track “The Archer,” which includes the lyrics, “I've been the archer / I've been the prey / Who could ever leave me, darling? / But who could stay?.”
In another video taken during the show, the NFL star — who is clearly a Swiftie — was also seen singing and dancing along to Swift’s song “Blank Space” as she performed.
Kelce also showed love to fans during the night. At one point, the tight end was filmed by a concertgoer making a heart sign with his hands while being led through the crowd.
Kelce’s appearance at Swift’s show comes after the pair spent a date night in Buenos Aires on Friday, after the tight end was spotted arriving in the South American country the same day.
Kelce was "beaming" during the evening, and he and Swift "looked so cute on their low-key date night,” a source told PEOPLE.

"They also left holding hands … and the crowd in the restaurant briefly cheered as they walked out," the insider added.
Kelce had previously hinted to his brother, Jason Kelce, on their podcast New Heights with Jason and Travis Kelce this week that he would be joining Swift in Argentina.
The pair’s union in South America comes after Swift was seen first attending a Kansas City Chiefs game in Missouri on Sept. 24. A source then told PEOPLE in late October that the pair’s romance was becoming "more serious."
