Oh, how the roles have reversed.

Travis Kelce was spotted watching his girlfriend, Taylor Swift, take the stage in Buenos Aires, Argentina, Saturday night during her Eras Tour.

The Kansas City Chiefs tight end was caught by fans in a VIP tent at River Plate Stadium alongside the pop star’s dad, Scott Swift.

Kelce looked to be enjoying himself while dancing in the crowd as Taylor performed “Willow.”

He also showed off his own vocal chops while being recorded by the singer’s father.

The athlete has apparently made a positive impression on Scott, who was seen rocking a Chiefs lanyard around his neck during Saturday’s sold-out concert, per photos obtained by the Daily Mail.

According to the outlet, Kelce met the singer’s dad for the first time during the couple’s cozy dinner date at Elena restaurant on Friday evening.

The NFL player, 34, touched down in Argentina that morning after attending his teammate Patrick Mahomes’ charity event in Kansas City, Mo., the night prior.

Scott appeared to give his stamp of approval by wearing a Kansas City Chiefs lanyard.

While Taylor, 33, couldn’t attend the gala alongside her beau, she donated a platinum record to the silent auction, which raised money for the quarterback’s 15 and the Mahomies Foundation.

Meanwhile, she kicked off the international leg of her stylish Eras Tour with a bang Thursday.

Despite Kelce’s absence, many fans believe Taylor sent the football player a not-so-secret message during her show.

Kelce missed the first night of Taylor’s concerts in Buenos Aires while at a charity event in Kansas City, Mo.

The “Cruel Summer” songstress, who performs two surprise songs each night of her tour, decided to sing “The Very First Night” and “Labyrinth,” the latter of which features telling lyrics.

“Oh no, I’m falling in love again,” she sang over and over while trying to subdue a smile.

Taylor had been set to perform in Buenos Aires Friday night, too, but she was forced to postpone the show — just hours after Kelce’s arrival — to Sunday because of rain.

While there have been rumors for weeks that Kelce was going to visit Taylor in Argentina, Page Six exclusively reported Wednesday that the football player was officially set to make the trek.

An insider close to the situation told us that the athlete was planning to catch at least one of Taylor’s shows before flying back for practice Monday.

The Chiefs are next scheduled to play on Nov. 20 when they take on Travis’ brother, Jason Kelce, and the Philadelphia Eagles — which also happens to be Taylor’s home team.

While it is unclear whether the 12-time Grammy winner will be in the stands for that game, she notably has the day off from her tour.

Taylor has cheered on the two-time Super Bowl champion at four out of his last seven games.

Although the duo have only been dating for a few months, they reportedly fell hard and fast.

Earlier this week, sources told Us Weekly that despite Taylor’s hectic tour schedule, the lovebirds came up with “detailed plans” to make their long-distance relationship work.

“Travis and Taylor are a very real couple; they actually spend a lot of one-on-one time together and have developed a very real connection,” an insider shared.

“They have very detailed plans coming up on how to stay together while she’s on tour and he has games.”
