Travis and Jason Kelce detailed their recent meeting with Prince William, Prince George, and Princess Charlotte during Taylor Swift's concert in London.

The Kansas City Chiefs star tight end recounted his experience of seeing Prince William for the first time during the latest episode of the New Heights podcast.

"He was so cool," Kelce said. "Obviously, we were backstage meeting him. He was there with little George and Charlotte. They were an absolute delight to meet. Wasn't sure if I was supposed to bow to them, curtsy, just be an American idiot and shake their hand."

"I gotta say, Prince William was fantastic meeting him," the former Philadelphia Eagles All-Pro center added. "But the highlight was Princess Charlotte. She was so f--king adorable. I don't know, maybe it's because I have three girls now. She had fire to her, she was asking questions."

The 14-time Grammy Award-winning musician posted a photo on social media after one of her shows in London, showing the younger Kelce as well as the Royal Family.

As he waits for Chiefs training camp to begin on July 21, the Kansas City tight end is enjoying his experience with meeting royalty across the pond as he supports Swift on her tour.
