Kate Middleton and Prince William’s three children are growing up quickly, and the youngest, Prince Louis, now has his own favourite superhero, according to the Duchess of Cambridge.

Earlier this week, Kate and Prince William paid a visit to the Wheatley Group in Glasgow, where the royal couple met with Joanne Wales.

The Wheatley Group tenant, who has four children, struck up a conversation with the Duke and Duchess of Cambridge, during which her son Jason showed Kate his toys, which included a Spider-Man and Hulk figure.

Kate responded, “Louis, our little boy, loves Spider-Man as well.”

“They were absolutely lovely and straight away they were talking to Jason about superheroes,” Joanne later told Hello! magazine of Kate and William’s visit.
