Prince George and Prince Louis are the eldest and the youngest sons of Kate Middleton and Prince William, and while the Duke and Duchess of Cambridge reveal tidbits about their boys at some royal engagements, a few insiders have shared more information about the royal brothers.

According to celebrity chef Aldo Zilli, Prince George, the third in line to the throne, has a favorite classic Italian meal. Apparently, the seven-year-old royal loves spaghetti carbonara, especially if it's prepared by Zilli.

Speaking with Daily Mail, the Italian chef said that he's actually waiting for Prince William to give him a call so that he can cook for the Cambridges again. Zilli said that he loves to cook for Prince George because he doesn't waste a single spaghetti strand of his carbonara. That's how much he loves the food!

During one royal engagement, Kate did share that she and her kids whip up pasta dishes in their kitchen because they love Italian food. Preparing a creamy pasta dish is a group effort, with one of the kids stirring the flour while the other adds the milk and butter.

Kate also shared that her kids love pizza. George and his sister, five-year-old Princess Charlotte, like to get their hands messy by making their own pizza dough.

Two-year-old Prince Louis, on the other hand, likely has no favorite food yet. But royal fans are curious if the youngest Cambridge child will soon start formal school in January 2021.

According to Hello, George and Charlotte started nursery school around the same age as Louis's current age. George attended the Westacre Montessori School in the countryside in Norfolk since Prince William and Kate were still staying at Anmer Hall at that time. Charlotte was enrolled at the Willcocks Nursery School in London when George attended Thomas's Battersea in his kindergarten year.

Speculations are that Louis might also go to the same nursery as Charlotte since it's quite near Kensington Palace. His two older siblings are staying put at Thomas's Battersea as they are in Year 1 and Year 3, respectively.

However, Prince William and Kate might also reconsider sending Louis to in-person classes until April, when it's safer. By then, vaccines against COVID-19 should be largely given to the U.K. population. The country is the global first to clear and authorize Pfizer's vaccine for public use with the first shots expected to be injected among carehome residents this December.
