"Her engagement at the Invictus Games and her most special meeting with HRH Prince Harry and his new wife Meghan has brought her so much joy, as they have done to others who watched on".
The Sussexes first post, shared on Tuesday afternoon, quickly attracted attention.
Kensington Palace recently announced new guidelines for its social media channels covering the former "Suits" actress and Kate Middleton amid reports of months of online abuse of the two members of the royal family.
The caption reads: "Welcome to our official Instagram; we look forward to sharing the work that drives us, the causes we support, important announcements, and the opportunity to shine a light on key issues".
Dunne spoke at length with the expectant parents and patted Harry's face affectionately as she congratulated the couple on their exciting news. "We hope you have a wonderful celebration surrounded by family and friends and that you've managed to escape hospital".

Meghan Markleand Prince Harry are using only the purest of products to ensure the safe arrival of their baby.
As you may already know, the former Suits star deleted all of her personal social media accounts before officially becoming a Duchess previous year.
The main reason? "They are very aware that the former blogger has more experience with this than they do, but they want to make clear that once something has been posted it can not be removed", explained the source, adding, "The experience of using social media as a royal and as an actress is very different".
Kensington Palace doesn't seem to mind: The "Kensington Royal" account promoted the new "Sussex Royal" account on Instagram, too.
