And on the back, there's a kind message from the duchess: 'The Duchess of Sussex is so touched you took the trouble to write as you did on the occasion of her 37th birthday. It really was thoughtful of you and Her Royal Highness sends you her heartfelt thanks and best wishes.'
Understandably, the newest member of the Royal Family was inundated with well-wishes for her special day.
Now, Meghan has sent out a very sweet 'Thank You' card to those that wished her a Happy Birthday.
Reporter Omid Scobie Tweeted a photo of the sweet card, 'A look at the latest 'Thank You' card being sent out by Kensington Palace on behalf of Duchess Meghan to those who wished her a Happy Birthday.'
