Incredible subtle detail in Travis Kelce's outfit that is sending Taylor Swift fans into a frenzy

Fans across the globe were absolutely buzzing when Taylor Swift brought her boyfriend, Travis Kelce, out on stage for the first time ever last night (23 June).

Swift, 34, took to the stage at London’s Wembley Stadium in the latest stop on her Eras Tour where she brought out the Kansas City Chiefs star during a heartfelt performance of 'I Can Do It With a Broken Heart'.

Now, Swifties were already super quick to notice Travis' incredibly sweet gesture in the VIP tent, but they've now been sent into a total frenzy after clocking one incredible subtle detail in his outfit.

Travis entered the stage dressed in a fabulous tuxedo and sparkly top hot ensemble, posing as one of the back-up dancers.

As part of the Eras Tour act, he picked up Taylor - who was pretending to be dead on the stage floor - and carried her over for her outfit change bit.

He then applied some make-up to her face with a brush as part of the bit before busting a little groove and leaving the stage.

However, eagle-eyed fans were quick to notice one particular detail in his get-up that they're going wild for.

It turns out there was one detail about Kelce's outfit that made him stand out from the other backing dancers - his shoes.

Like Swift, Kelce was wearing Louboutins, famous for their red soles.

Red, as luck would have it, is also the colour of the Kansas City Chiefs.

The attention to detail here is really extraordinary.

Fans loved picking up on Kelce's shoes in the comments, with one writing: "This was super planned!!! He even has matching Louboutin shoes."

"I was just coming here to say this is the first time I’ve seen his soles are red too," added another.

And a third resolved: "Yep Chiefs red."

Others were just thrilled to see Travis up on stage with Taylor.

One fan captioned footage from the gig: "TRAVIS KELCE HAS OFFICIALLY LAUNCHED HIS ERA!"

He sure has.

Another noted the significance of Kelce appearing during 'I Can Do It With a Broken Heart', writing: "Travis picked her up when she had a broken heart and in London."

A third said: "They are just collecting memories for their grandkids at this point."

Well, hopefully we'll be seeing a whole lot more Trav and Tay action on stage from now on...
