The Duchess of Sussex, who turned 38 on August 4, mailed special responses to fans who sent in letters to celebrate her birthday, as seen in a tweet shared by royal fan Christin Zi. Meghan chose a photo from her 16-day tour of Australia, Fiji, Tonga and New Zealand with Prince Harry this past fall — which kicked off with the announcement that the royal couple were expecting their first child! In the shot, Meghan clasps her hands together and has a big smile on her face as she sits in a sky blue dress.
