Prince Harry was joined by Barack Obama at the Invictus Games in Toronto to surprise the American wheelchair basketball team.
The former US president and his White House second-in-command Joe Biden cheered on the team as they took on France at the games on Friday.
Mr Obama and Harry were all smiles and laughter as they posed for photos with young fans at the Paralympics-style event for wounded and disabled service personnel and veterans.
Also in attendance at the Pan Am Sports Centre was Jill Biden, former second lady of the United States, who said she was “thrilled” to cheer on Team USA.
After posing for pre-match photos with the American team, the foursome sat in the front row for the event.
Harry on Sunday played host to US First Lady Melania Trump and Canadian Prime Minister Justin Trudeau at the Invictus Games.
The event, founded by Harry in 2014, aims to aid the recovery of military personnel whether they are wounded in combat or outside of their service.
