Eyewitnesses who were at Windsor Castle for the Maundy Thursday service saw Meghan and Harry, who reportedly smiled and waved at them.
One eyewitness said: “I couldn’t believe it when I saw who it was. We waved and they waved back.
“They looked happy and relaxed and waved to everyone on the bus.
“Charles and the Queen were at Windsor Castle at the same time so they must have met them both.
“It was quite the sight. We knew we might see Charles and the Duchess of Cornwall at the ceremony but never believed we would bump in to Harry and Meghan.”
