The pop star, 33, sent Swifties into meltdown as she changed the lyrics to hit song Karma to include a few words about her NFL star boyfriend, who was watching in a VIP tent alongside her dad on Saturday night.

Swift sang ‘Karma is the guy on the Chiefs coming straight home to me’ to replace the original lyric, ‘Karma is the guy on the screen coming straight home to me’.

Like most things the couple do, it sent social media into a frenzy and caused a surge in Google searches looking for tickets to watch a Chiefs game – where Swift had regularly been seen before her hit tour restarted.

Analysis of Google search data by Fr-CasinoSpot has revealed that online searches for ‘Chiefs tickets’ exploded 150 per cent worldwide after the shoutout.

But it appears a number of Swifties still have no idea what she was referring to in the song because searches for ‘what is chiefs’ saw an incredible 289 per cent increase worldwide.

Alongside searches for tickets, worldwide interest in searches for ‘Kansas City Chiefs’ skyrocketed 496 per cent after the concert, proving just how keen fans of Swift are to find out more about Kelce’s team.

revealed that the NFL star flew out of Kansas City at 11pm on Thursday – making a one-hour stop in Panama City to refuel – before flying into Buenos Aires to reunite with Swift Friday afternoon.

He was set to watch two of the star’s Buenos Aires shows, but the first was postponed because of torrential rain – allowing her to have dinner with her NFL beau at the Four Seasons exclusive Elena restaurant instead.

Kelce, 34, spent Saturday night dancing and singing in a VIP tent at Swift’s Argentinian Eras Tour leg, alongside her father Scott.

A viral video captured the moment Kelce heard Swift’s improvisation, as it showed the superstar athlete smacking his hands to the side of face in utter astonishment, before he broke out a few smooth dance moves.

The lyric change wasn’t the only moment Taylor had Travis on her mind, as she also sang to him directly and mouthed the lyrics ‘that’s my man’ during her performance of ‘Willow’.

At the end of the show, Kelce was waiting in the wings to greet his girlfriend and the smitten Grammy winner ran into his arms before they shared a kiss.

In an apparent seal of approval, Scott — who was only just recently introduced to Kelce — was photographed wearing a Chiefs lanyard around his neck despite being a huge Philadelphia Eagles fan.

Kelce made a McDonald’s pit stop before dashing onto a private plane on Sunday to make it back in time for Chief’s practice.

After departing his luxury four-star hotel, Kelce and three members of his security team made a short stop at a nearby McDonalds, though the tight end left empty-handed.

Donning the same green baseball cap he wore to arrive, Kelce wore a beige tracksuit to board the plane.

The star jogged up the stairs of the private plane after a short delay at the airport, taking off at 12.30pm.

After Taylor attended four of Kelce’s games this season, the NFL star returned the favor during his downtime.

The Chiefs were on a bye week but he’ll play against brother Jason and the Philadelphia Eagles in a repeat of this year’s Super Bowl on Monday night.

Swift has been showing her support for her new beau by attending several games at Arrowhead Stadium, and hosted a watch party for the WAGs at her New York apartment as the Chiefs took on the Miami Dolphins on Sunday.
