‘American idiot’ Travis Kelce details meeting Prince William at Taylor Swift’s Eras Tour show

Travis Kelce met the “coolest motherf–ker” at Taylor Swift’s London Eras Tour show — Prince William.

The athlete gushed about the Prince of Wales on his and Jason Kelce’s “New Heights” podcast Wednesday, noting that he wasn’t sure whether he was “allowed to” talk about the major moment.

“He was there with little George and Charlotte,” Travis, 34, said of William and Kate Middleton’s 10-year-old son and 9-year-old daughter.

“They were absolutely a delight to meet,” he gushed. “I wasn’t sure if I was supposed to bow to them, curtsy, just be an American idiot and shake their hands, like, ‘Sup, dude.’ We wanted to be polite.”

Jason, 36, clarified that, because they weren’t at an “official royal event,” there was no need for bowing.

The former Philadelphia Eagles player did, however, “feel emasculated” and put his “beer, like, 10 feet away.”

Travis joked, “I’ve never seen you give someone that much respect.”

The brothers went on to praise William’s parenting, with the Kansas City Chiefs tight end explaining that the royal clearly let his “kids be vocal.”

Jason called Charlotte “the most electric part” of their interaction.

“Prince William was fantastic, but the highlight was Princess Charlotte,” he told listeners. “She was so f–king adorable.

“Maybe because I have three girls now, [but] she had a fire to her,” Jason continued. “She was asking questions.”

Elsewhere in the episode, the siblings broke down Swift’s “amazing” concert, with Jason admitting it made him “tear up.”

The pair seemingly recorded the episode after attending Friday’s concert together — but before Travis took the stage with Swift during her Sunday show.

Although the “Catching Kelce” alum has yet to speak about the surprise moment, he did tease via Instagram that there are “more memories to come.”

In a post of her own, Swift gushed that she was “cracking up/swooning” over her boyfriend carrying her onstage during the “I Can Do It With a Broken Heart” skit transition.

The couple have been dating since the summer of 2023.

Travis and the pop star made their Instagram debut over the weekend when Swift shared their selfie with William and his two eldest children.

One week before the royal meet-and-greet, Jason made headlines for declaring “f–k kings” on the podcast.
