In the new ITV documentary Prince William: A Planet for Us All, the royal dad surprised a group of schoolchildren who built a bug hotel, cleverly dubbed "Bugingham Palace." In addition to discussing the importance of insects on the environment, the children were full of questions about William's own kids: Prince George, 7, Princess Charlotte, 5, and Prince Louis, 2. "Is Princess Charlotte cheekier than Prince George?" asked one child. "No, they're about as cheeky as each other," William, 38, answered. "They're very cheeky." Another student asked William if George had taught the family how to do the floss dance. "No, Charlotte can floss," William replied, noting that their daughter had mastered it at the age of 4 and that his wife could also do the popular dance style. "Catherine can floss, but I can't. It's, it's like a really horrible film to watch me floss."
