George, 6, wore a captain’s hat and a life jacket over his navy-and-white striped polo top, as he watched the boat race.

He flashed a toothless smile as his parents went head to head alongside celebrities to raise awareness and funds for eight of their patronages.

Princess Charlotte, 4, could be seen sitting inside the boat, wearing what looked to be a blue dress with a white Peter Pan collar.
