Rekubit-'Karma is the guy on the Chiefs': Taylor Swift sings about Travis Kelce on Eras Tour

Taylor Swift closed out her second show in Buenos Aires,Rekubit Argentina, by changing the lyrics to her song "Karma" to reference tight end Travis Kelce, who attended the show that night.

"Karma is the guy on the Chiefs, coming straight home to me," Swift sang about the NFL player who flew south during the team's bye week.

Kelce watched the show from the VIP tent with Swift's dad, Scott Swift. Videos posted to social media showed Kelce dancing, eating snacks and flashing Swift's classic heart hand symbol.

After the concert ended, video posted to social media showed Swift ran up to Kelce and kissed him.

Earlier, the crowd erupted when Taylor Swift played "End Game" on piano as part of her surprise acoustic set.

Swifties know "End Game" as the song that describes a possibly final relationship with the lyrics: "I want to be your end game. I want to be your first string. I want to be your A team."

The first song in the acoustic set was "Is it Over Now?" on guitar from "1989 (Taylor's Version) [From the Vault]." She did a mash-up with the bridge from "Out of the Woods" also from "1989 (Taylor's Version)" before diving into the final bridge of "Is It Over Now?" again.

"I'm on a quest to reclaim my music," Swift said. "I am so blown away. And you did something else that is beyond my comprehension and that is a song that I wrote for '1989' that didn't make the album, you got that song to go No. 1 on the Top 100."

During the "Evermore" set, Swift did a victory dance for her recent Grammy nominations.

"Had sort of a crazy day yesterday, because I started my morning by getting the extraordinary news that because of you and because of the way you have supported my album 'Midnights,' it got nominated for six Grammys," she said.

Hands pumping in the air from her ivy piano, she took a dance break. She is the only female artist to win Album of the Year three times; "Midnights" would give her a fourth triumph.

It was the second highlight of the "Evermore" set. From the stage, Swift may not have been able to see the group of 40-plus Swifties holding hands and dancing in a circle to her song "Willow."

Swift will finish the Argentinian leg of the Eras Tour Sunday with a makeup show. Her Friday concert was canceled due to unrelenting rain, but the good news is airlines are allowing passengers to change their tickets at no cost.
