Schofield, whose new book published by Simon & Schuster, R is for Revenge Dress is set to release on November 15, said: "My heart really broke for the memory of Princess Diana as I watched how beautiful and happy the Cambridge family were throughout the Jubilee celebrations.
"Diana would have been so tickled! Prince Louis is naughty and cheeky and precious… just like his grandmother Di."
She continued: "Diana would be proud of Prince William and his family. Wills is the best parts of his mother and his father.
"The Duke of Cambridge has his mother’s heart and his father’s head. Not to mention Princess Diana’s gorgeous looks. What a handsome man!"
