Ahead of the Euros final, on 10 July, 2021, Kate shared a snap to Instagram of the good luck letter she sent to Harry before the big game. The heartfelt tribute was full of anecdotes from the early days in their relationship. Kate began the letter: "H, you know I am not one to cry too easily but I found myself in tears when I started writing down how proud you're making us all and what you're doing for the country. I used to laugh at you when we started going out and you'd be round at mine playing penalties with my brother Tom and Seamus the dog, and you'd say you would be England captain one day. But that's you - you set yourself a goal and you achieve it and you always said you were going to the Euros to get to the final."
