The prince has been too busy focusing on what his own children want for Christmas to think about what he'd like, but at the top of his wishlist would be a win for his beloved Aston Villa FC over Chelsea on Boxing Day.
He said: "If I have to say right now, I would say it would be for my favourite team, which is Aston Villa, to win their football match on Boxing Day."
William joked that he's "saving up" to buy a "bright yellow" sports car when he's older in response to another question from a child.
He said: "Fiona, I wish! I would love to have a Lamborghini. A big, bright yellow Lamborghini.
"But no, unfortunately, I don't have a Lamborghini. I'm going to have to save up for one of those when I get older."
William took a more serious turn when asked what he'd do if he was in charge of Christmas for a day.
He said: "I think I'd have to make sure everyone could enjoy it. So we'd have to bring everyone together, have a big party.
"There would definitely be no Covid, and there certainly would be no cancer in the world if I was in charge of Christmas for the day. How's that? Is that a good enough answer?"
