This appearance is fodder for another rumour, too: That Donald Trump will make good on his threat to deport Prince Harry — or as the president-elect phrased it, take “appropriate action” if he could prove the royal lied on his visa application about the drug use he details in his memoir — once he takes office.

During Prince Harry's appearance on TSN, he mentioned that this was his first time attending the Grey Cup. "Really looking forward to the game getting started," he said of the Canadian Football League's championship game between the Winnipeg Blue Bombers and the Toronto Argonauts. "Let's go!" he added when speaking with commentator James Duthie.

Prince Harry surprised football fans Sunday, appearing at the Grey Cup in Vancouver before the Toronto Argonauts took on the Winnipeg Blue Bombers. Wearing a dark dress shirt and long, black jacket, the Duke of Sussex was interviewed by TSN’s James Duthie at the station’s sideline set, then waved at the crowd before he was quickly escorted away.
