Kate Middleton and Prince William have been married for over 20 years. The couple have four children together: George, Charlotte and Louis.
Prince William is said to be a real hothead in his private life, where the fuses blow. Kate treats him like the fourth child because he's prone to tantrums, an insider said. The future royal couple would have taken the motto of Queen Elizabeth as a model: "Never complain, never explain".. Kate has everything under control – including the occasional tantrums of her husband Prince William.
