Taylor Swift looks enamored as she offered a not-so-subtle shoutout to her boyfriend Travis Kelce, who was in Argentina for the Eras Tour on Saturday.

The 12-time Grammy winner, 33, rewrote the words of her hit song, Karma, to disclose her relationship status with the Kansas City Chiefs tight end, 34, while playing at Buenos Aires’ Estadio River Plate in Argentina.

On social media, a fan released a concert clip in which Swift can be heard singing, “Karma is the guy on the Chiefs coming straight home to me.” After she says the line, the musician can be heard chuckling.

Kelce was also seen cheering on Swift from the VIP tent during the show. He was also seen in the tent with the musician’s father, Scott Swift, who was wearing a Chiefs lanyard, and opening performer Sabrina Carpenter later joined him.

Kelce was noticeably astonished and blushing when Swift delivered the new words, while Swift’s father was seen celebrating and laughing with him.

Swift and Kelce were previously seen on a date in the city, dining in a private room at Elena restaurant at the Four Seasons Hotel Buenos Aires.

According to People Magazine, the NFL star was “beaming” throughout the evening, and the couple looked “cute” as they exited the restaurant “holding hands.”
