Shortly after the couple shared the news with the world, members of the British royal family took to Instagram to congratulate the couple.
"Congratulations to The Duke and Duchess of Sussex on the birth of Lilibet Diana!" the royal family wrote in a joint statement on Instagram, alongside a photo of Markle and Harry that was taken on their wedding day in May 2018.
"The Queen, The Prince of Wales and The Duchess of Cornwall and The Duke and Duchess of Cambridge are delighted with the news. Lilibet is Her Majesty's 11th great-grandchild," the post continued.

The palace shared a similar statement with the press on Sunday. It read: "The Queen, The Prince of Wales and The Duchess of Cornwall, and The Duke and Duchess of Cambridge have been informed and are delighted with the news of the birth of a daughter for The Duke and Duchess of Sussex," the statement said.
"Congratulations dear cousins," she wrote across the photo, along with six red heart emojis. "We couldn't be happier for you all."
Lilibet Diana was born on June 4 and is named after both the Queen, whose family nickname is Lilibet, and the late Princess Diana, Harry's mother.
