“I did still address him as Your Royal Highness,” said Jason. “I’ve never felt emasculated [before] and I did. That was the closest I’ve ever been.”

His brother joked: “Dude, I’ve never seen you give someone that much respect. You put your beer down, like, 10ft away from you.

“They were wonderful people and that’s what it’s about,” said Jason.

Travis added they were “very genuine, very cool”, while his brother added that they seemed “honoured to be there to meet Taylor”.

The young Wales family made headlines at the weekend when photographs of them meeting Swift were posted on social media.

Prince William was captured on footage “dad dancing” to Swift’s song Shake it Off.

He has previously sung on stage, karaoke style, with Swift and Jon Bon Jovi.

Relaying the story to listeners of the podcast, New Heights with Jason and Travis Kelce, Swift’s boyfriend said of the 2013 royal engagement: “Tay got him out of his shell and sure enough they got up there, they ripped it, and they said he had a blast.

“I dunno if any other prince is doing that? He was cool enough to be a part of it. It just shows you how personable he is.”

Returning to the Eras tour night, Jason said the highlight was Princess Charlotte. “Prince George was great too. She was so f-----g adorable.”

“She was a superstar,” Travis agreed.

Jason said: “She had a fire to her, she was asking questions. That was the most electric part.”

Travis added: “I love it when parents ask their kids to be vocal. It’s such a great parent move.”

The brothers ended the section by joking that “we’re not even sure if we’re allowed to tell you that”.
