Luke Vincent, The Six-Year-Old Who Stole Harry And Meghan's Heart (And Ours)

He only recently announced to the world that he and wife Meghan Markle are expecting their first child together.

But if Prince Harry's recent interactions with children is anything to go by, this royal is well and truly in full training mode for impending parenthood.

After hopping off the plane in Dubbo, Harry was greeted by a group of school children who were all lined up neatly behind a white rope.

The royal and his new wife diligently shook each and every hand, and even got on bended knee to chat with the school children.

But it was when Harry reached the end of the line and met six-year-old Luke Vincent all that protocol was thrown out the window.

Luke, who was holding the hand of his principal, Anne Van Dartel,  broke away from her and embraced the father-to-be. Clearly overcome with emotion, Harry placed his arms around Luke and stroked his back.
