Taylor Swift gave a significant shout-out to beau Travis Kelce during her concert in Buenos Aires on Saturday night — and his reaction was priceless.

The pop star, 33, sent Swifties into a frenzy, as she changed up the lyrics to her hit song Karma to include a few words about her new Kansas City Chiefs boyfriend, who was supporting her from the VIP tent alongside her dad.

Surrounded by her backup dancers on stage at the Estadio River Plate stadium, Taylor belted out ‘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’.

A viral video captured the adorable moment Travis heard the epic 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’.

Adding to the fan hysteria, the Grammy winner ran into Travis’ arms and planted a passionate kiss on him after the curtain call.

In a now-viral clip shared to social media, Swift is seen walking off stage in a sparkly purple dress and immediately wraps her arms around Kelce, 34, who was waiting stage left for the Anti-Hero singer.

The couple then pressed their lips together and shared a seconds-long smooch that sparked deafening screams from Swifties, who were lucky enough to watch the PDA unfold.

DailyMail.com exclusively revealed that Kelce — who touched down in Argentina on Thursday — was in the audience for the sold-out show Saturday with Swift’s dad Scott Swift. Photos revealed that they were located in a VIP tent within the massive stadium with a perfect view of the stage.

The Bad Blood hitmaker winked in her new beau’s direction during the show as he shared a laugh and joke with her businessman father in the spacious hangout.

While performing the song Willow from her Evermore era, Swift sang to Kelce directly and mouthed the lyrics: ‘That’s my man.’

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

She appeared to put in extra effort for her Lover, who sang along to all of her best hits and danced in front of fans.

When the multi-Grammy winner started to perform her hits from her Reputation Era, Kelce looked visibly impressed and was spotted mouthing ‘wow’.

While performing her 2017 hit song, Delicate, she pointed towards the VIP box and appeared to be singing directly to Kelce as she mouthed the words: ‘You must like me for me.’

She also pointed to the football star as she continued singing: ‘Is it cool that I said all that? / Is it chill that you’re in my head?’

Her father filmed her during the song and then turned to continue chatting with Kelce.

Kelce joined in chants of ‘olé olé olé’ before turning to her father’s phone, which captured him yelling ‘Taylor Taylor’ in support of the superstar after she mentioned her Grammy nominations.

She also sang End Game for her surprise song at her show with Kelce watching and listening closely and attentively.

‘I wanna be your endgame,’ she sang the lyrics, which seemed to be directed towards him.

When Swift sang the line, ‘You know I love the players’, she pointed at the football star as fans screamed in delight.

The tight end also clapped and beamed when Swift announced to the stadium full of her fans and supporters that her latest album, Midnights, had been nominated for six Grammys.

Dressed in another fashion forward shirt, the football player slipped into the show minutes after Swift appeared on the stage under a cloud of pink and purple butterfly wings.

The blonde bombshell put on a performance for the fans, with Kelce and her father posing with ‘We Will Stay’ posters during the Archer – a movement with the Argentinian Swifties.

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

Taylor and Travis kicked off their romance in late September after weeks of dating rumors and the NFL star’s failed attempt to give her his cellphone number in July.

They went public with their romance during his September 24th football game, and have been spotted on numerous outings since.

The singer has attended four of his games so far, and he is expected to stay for all of Swift’s shows in Argentina this weekend.

She introduced Kelce to her father on Friday night as they dined in Buenos Aires — just hours after the football star flew in to see her.

The pair were able to enjoy each other’s company during a meal at the restaurant, alongside Scott, 71, after bad weather forced the star to call off her second performance.

Sources told DailyMail.com that the pair enjoyed a steak – which cost upwards of $75 dollars at the Four Season’s luxury restaurant – and were relaxed and happy to chat to staff who served them for several hours.

At least six members of kitchen staff formed a guard of honor around the couple as they left, with several diners cheering as the trio made a swift exit through an emergency door.

Last month, DailyMail.com learned that Swift has been blown away by the way the sports star has ‘courted her’ like a ‘gentleman’.

An insider close to Taylor’s celebrity pal Lively revealed that while the songstress was ‘trying to keep it together,’ it was obvious to those around her that she was already ‘falling’ hard for her new beau.

‘Taylor is blown away right now and her family is all about Travis. She is trying to keep it together, but is obviously falling in love with him and he feels the same way,’ they dished.

‘He courted her and it was not her typical, “Hey, you’re hot, let’s go out,” sorta thing. He actually courted her and she feels like she is the luckiest gal in the world right now.

‘It is no coincidence that all she had to do was look outside of Hollywood.’
