Forget Prince William’s dancing — Jason Kelce says Princess Charlotte was the highlight of Taylor Swift’s Eras Tour

• Jason and Travis Kelce discussed their recent attendance at the Eras Tour on their podcast.
• They revealed that they both met the royal family at Friday's show in London.
• Jason said Princess Charlotte was "the highlight" of the interaction.

Jason Kelce has a new favorite royal: Princess Charlotte.

Over the weekend, Taylor Swift continued her European leg of the Eras Tour with three shows at Wembley Stadium in London. The London Authority estimated that Swift's shows boosted the city's economy by about $379 million.

The weekend was filled with fun moments, including Swift bringing her boyfriend, Travis Kelce, who attended all three shows in London, onstage for a surprise appearance on Sunday.

The Friday and Saturday shows also marked Travis' brother and sister-in-law Jason and Kylie Kelce's first stops on Swift's Eras Tour.

The couple were just two of several celebrities who attended the London shows. At one of the performances, they met three of the most famous people to ever come to a Swift show: Prince William, Prince George, and Princess Charlotte.

Prince William brought his kids to the Eras Tour

William attended the concert on Friday with George, 10, and Charlotte, 9. Kate Middleton and Prince Louis, 6, did not join them.

In addition to watching the show from a private suite, the trio visited Swift and Travis backstage before she performed.

The Prince of Wales and Swift posted about their meetup on Instagram.

Swift's interactions with the Waleses bolstered positive attention for the royals, as did a video of Prince William dancing gleefully to "Shake It Off" during the concert.

The Kelce brothers shared new details of the meeting on Wednesday's episode of their podcast "New Heights," during which they revealed Jason and Kylie also met the royals.

Travis and Jason said they were impressed by the family.

"They were an absolute delight to meet," Travis said on the podcast of the royals. "I wasn't sure if I was supposed to like bow to them, curtsy, just be an American idiot and shake their hands."

"They said because we weren't at like an official royal event, we didn't need to bow or curtsy," Jason said. "I did still address them as Your Royal Highness."

"I've never seen you give someone that much respect," Travis told Jason. "You put your beer like 10 feet away from them."

"They were wonderful people," Jason said, adding that they seemed "down to earth."

The brothers also said they were fans of William, with Jason saying he is "a good dude."

"He was the coolest motherfucker," Travis said of the heir to the British throne. "He was so cool."

Princess Charlotte left an impression

Jason said that meeting Princess Charlotte, who was grinning from ear to ear in her photos with Swift, was "the highlight" of his interaction with the royals.

"I gotta say, Prince William was fantastic, but the highlight was Princess Charlotte," Jason said. "Prince George was great, too."

"She was so fucking adorable," Jason went on to say of Charlotte. "Maybe it's because I have three girls now."

Jason and Kylie have three daughters: Wyatt, 4, Elliotte, 3, and Bennett, 1.

"She was a superstar," Travis agreed of Charlotte.

"She had fire to her," Jason added of the princess. "She was asking questions. That was the most electric part."

Charlotte also stood out at Trooping the Colour on June 15, where she was spotted looking like the spitting image of her father.
