Brothers Jason Kelce and Travis Kelce had a casual encounter with Prince William backstage at the Eras Tour in London, where they were given a quick lesson in royal protocol before officially meeting the prince and his children, Prince George and Princess Charlotte. Travis described Prince William as "the coolest motherfuker," while Jason admitted to feeling slightly emasculated addressing him as "Your Royal Highness." Despite receiving warnings on proper etiquette, the brothers were informed that they did not need to bow or curtsy since it was not an official royal event. The encounter was a mix of excitement and humor, with Jason's previous comment of "fuck kings" on a podcast causing a moment of panic for Travis. This meeting with royalty left a lasting impression on the Kelce brothers, as they recounted the experience with humor and awe.
