Kate Middleton’s birthday might have been in January, but fans are just now receiving their Royal Mail thank you cards. Kensington Palace responded to all of the well-wishes sent to the Duchess of Cambridge with a previously unseen picture of Kate. “The Duchess of Cambridge thanks you for taking the trouble to write on the occasion of her 38th Birthday,” the card reads. “Your thoughtfulness was greatly appreciated by Her Royal Highness who sends he warmest thanks and best wishes.” The new picture was taken in 2018 during a family photo session with photographer Matt Porteous and features the duchess sitting on a fence in a casual look.
