The NFL star said he had never seen his brother Jason Kelce “give that someone that much respect” to someone as he did when they met the Prince of Wales at Wembley Stadium on June 21

The NFL tight end added that when he first met William and his children Prince George, 10, and Princess Charlotte, 9, backstage at the show, he wasn’t sure what the protocol was and whether he should “bow,” “curtsy” or “just be an American idiot and shake their hand.”

“We wanted to be polite, especially on this side of the park,” he noted.

He also shared that Jason, 36, got to meet Prince William and his kids and noted that he had never seen his brother “give that someone that much respect” when he met them.
