If Travis Kelce hasn’t already won over Taylor Swift’s Aussie fans, his sweet gesture during her first Sydney show will surely seal the deal.

After touching down on Thursday, the 2024 Super Bowl champion attended the first of his girlfriend’s four shows – a surprisingly star-studded affair – in the NSW capital on Friday night.

Kelce was greeted by thunderous applause as he walked into Accor Stadium, joined by fellow NFL star Ross Travis and Swift’s father Scott Swift, and made his way to a VIP tent on the floor.

Later in the night, some lucky fans received a very special keepsake from the Kansas City Chiefs tight end, who has been dating Swift since September.

A video shared online shows Kelce reaching into his pockets to retrieve guitar picks belonging to the singer, before handing them over.

“Highlight of the show,” Tiktoker @ckritiiiiii_ captioned the video.

It’s a simple gesture, but it’s a sign of just how close Kelce has become with Swift’s family.

The multi-Grammy Award winner’s guitar picks have been handed out to fans during her shows for years, a responsibility usually falling to her parents.

Kelce also got right into the friendship bracelet movement that’s emerged throughout Swift’s Eras Tour, with a stack of the tokens seen on his arm.

Travis, who travelled to Australia with Kelce in a private jet on Thursday, was also decked out in the bracelets.

The American athletes made a colourful duo, wearing patterned t-shirt-and-shorts sets in blue and yellow.

Scott Swift was also spotted interacting with fans, handing out sandwiches and fruit to ticketholders on the stadium floor.

Kelce earned a sweet shoutout from his girlfriend during the concert, with Swift tweaking the lyrics to her song Karma in a nod to the athlete.

“Karma is the guy on the Chiefs, coming straight home to me,” she sang, replacing the original lyric “karma is the guy on the screen”.

It’s not the first time she’s sang that version of the song during her tour in a nod to Kelce’s presence, but it still sent her Aussie fans wild.

It’s not known how many of Swift’s Sydney shows Kelce will attend while in Australia.

The couple enjoyed some downtime in the Harbour City on Thursday, visiting Sydney Zoo in Blacktown.
