Not many people know that Prince Harry is really called Henry.
At the recent WellChild Awards, the Duke made the personal confession during a chat with the winners of the awards. Talking to a child named Henry, Prince Harry said via video call: "My name is Henry as well. But everyone calls me H."

Back in October, Harry's wife Meghan revealed the endearing nickname she has given her husband.
Speaking to Tom Bradby on their ITV documentary Harry and Meghan: An African Journey, Meghan let slip what she affectionately calls her husband.
She said: "In all honesty, I have said for a long time to H - that is what I call him - it's not enough to just survive something, that's not the point of life." She continued: "You have got to thrive. You have got to feel happy, and I think I really tried to adopt this British sensibility of a stiff upper lip."
Meghan Markle and Prince Harry
And in August 2018, the former actress revealed another pet name she has for her husband.
While posing with the cast of the musical Hamilton after a special gala performance, Meghan, worried that she was standing in Harry's way for the group shot, said: "Can you see, my love?"
After some of the cast fawned over their cute exchange, Meghan said: "Oh!" and then laughed bashfully while Prince Harry blushed.
