During her break from performing, she ‘loved catching up with girlfriends’ and ‘had fun spending time with Travis’ they added.

‘He (Kelce) is a gentleman. He is very focused on his career. He has a great relationship with his family. He has an amazing energy and approach to life.’

‘It all feels very special,’ they added.

Taylor Swift and Travis Kelce ‘s blossoming romance ‘all feels very special’, says an insider

A report from Yahoo Entertainment last month claimed the relationship between the singer and one of the stars of the NFL was getting serious.

A source told them: ‘They’re already making plans for the future.

‘He and Taylor have even talked about kids. Travis wants them in the next year or so, and Taylor, of course, is all in.

‘He’s exactly the guy she’s been waiting for. He said he can see himself marrying Taylor.’

The pop star, 33, sent Swifties into meltdown on Saturday night 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’.

Last week DailyMail.com exclusively revealed that the NFL star flew out of Kansas City 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’.

Kelce and Swift began dating in September, with Swift becoming a regular at Chiefs games

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.

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

But DailyMail.com exclusively then revealed 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.

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 shown 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.
