The 34-year-old American football star joined his girlfriend on stage for the first time at the Eras Tour concert at Wembley Stadium.

Talking about the origin of the skit on his podcast New Heights, Kelce told his brother and co-host Jason: “I initially mentioned it to Tay”.

“I was like, ‘How funny would it be if I just rolled out on one of the bikes during the 1989 era’.”

Swift initially laughed, he said – before asking, “Would you seriously be up for doing something like that?”.

Kelce said: “I was just like, ‘What? I would love to do that, are you kidding me? I’ve seen the show enough – might as well put me to work here.”

He appeared on stage dressed in a tuxedo and top hat, busting out a few dance moves before carrying Swift – who appears to faint – to a sofa.

That was the most nervewracking part of the performance, he said.

“The one thing I told myself is ‘do not drop the baby’. Do not drop Taylor on your way over this couch.”

The star then changed into a two-piece sequin costume – while Kelce pretended to top up her makeup – and performed I Can Do It With A Broken Heart from her latest album, The Tortured Poets Department.

Kelce said it was “an absolute blast” and an “honour” to join Swift on stage.

“It’s such a fun, playful part of the show.

“I didn’t disappoint Taylor, so that’s all that really matters,” he added.

Kelce also met Prince William and his children Prince George and Princess Charlotte at one of the Wembley shows.

A picture of the group was posted on Instagram on 21 June, the same day as William’s 42nd birthday.

On a previous episode of the New Heights podcast, Kelce said the Prince of Wales “was the coolest m*****f*****”.

“They were an absolute delight to me, I wasn’t sure if I was supposed to bow to them or curtsy, or just be an American idiot and shake their hand.”
