Travis Kelce calls Prince William 'the coolest'

Travis Kelce has dubbed Prince William "the coolest".

During Wednesday's episode of his New Heights podcast with his brother Jason Kelce, the American football star recalled meeting the British royal during his girlfriend Taylor Swift's Eras Tour show in London on 21 June.

"We met royalty guys, there was royalty at the show," Travis, 34, said. "I was lucky enough I got there early and got to meet Prince William. How about that? Your Royal Highness. He was the coolest motherf**king dude."

Jason, who declared that he was "out on honouring kings" in an earlier episode of the podcast, agreed with his brother.

"He was awesome," the 36-year-old said. "He was a good dude."

Prince William, 42, attended the concert with two of his children, Prince George, 10, and Princess Charlotte, nine, who he shares with his wife Catherine, Princess of Wales. The couple also share six-year-old Prince Louis.

"He was there with little George and Charlotte," Travis continued. "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, 'Sup dude.'"

Jason then revealed that they had been briefed on how to greet the royals.

"We did get warning," he said. "They said because we weren't at an official royal event, we didn't need to bow or curtsy. If it would've been an official meeting of royalty event, then it would've been that. But I did still address him as Your Royal Highness. I've never felt emasculated, and I did. That was the closest I'd ever been."

Travis added, "I've never seen you give someone that much respect - you put your beer like ten feet away from you."
