The US pop star was in the midst of her folklore set about halfway through her three-hour concert when she sighted boyfriend Travis Kelce, who popped up in the VIP tent at Aviva Stadium.

The NFL tight end had been a guest at the wedding of his Chiefs teammate Clyde Edwards-Helaire in California, before rushing to attend Swift’s Sunday night show – much to her surprise.

Swift’s priceless reaction was caught on camera by multiple fans.

A beaming Swift, who was singing august when she clocked Kelce, returned a wave before carrying on with her performance.

Elsewhere at the show, Oscar winning actor Julia Roberts joined the entourage in the VIP tent, where she caused a stir among Swift’s fans for being too “handsy” with Kelce.

The Pretty Woman star, 56, was seen rubbing Kelce’s shoulders and tickling his chest as she chatted and laughed with him in a video circulating on TikTok.

Roberts — who has been married to cinematographer Danny Moder since 2002 — could be seen grabbing Kelce’s arms as she said something that made him burst out laughing.

The touchy-feely encounter appeared mutual, as the NFL player warmly rubbed the actor’ arms and had a big smile on his face.

However, some social media users felt the encounter was inappropriate.

“Wow handsy much? The scratching?” one wrote on X.

“Her physicality with him is cringe!!” another added.

Swift is next set to perform three shows in Amsterdam as part of the Europe leg of her blockbuster tour, which will wrap with five sold-out shows in London in August.

She’ll then have a three-month break before hitting Canada, with six shows in Toronto and three in Vancouver, the latter of which will signal the end of the Eras Tour after a mammoth 21 months.
