While Prince Harry and Meghan Markle are likely caught up in the excitement of becoming first-time parents, they did not forget their niece's fourth birthday.
Princess Charlotte turns four today (April 2) and they shared a sweet message to her on Instagram.
To celebrate their daughter's birthday, the Duke and Duchess of Cambridge shared shared three photos of their adorable little girl which were all taken by Kate Middleton.
Meghan and Harry were among the thousands of people who commented on the sweet snap, which was taken by Kate.
They wrote "Happy birthday Charlotte! lots of love, H and M xo" with balloon and birthday cake emojis.

While most people loved the message, others were annoyed they didn't use the word 'princess'.
One wrote: "Even on Kensington Royal (her parents insta) she is referred to as Princess Charlotte. Meghan is just being disrespectful like she was to Prince Louis."
Another commented: "Even if they are related through Harry, she needs to call her Princess if other Royals call her that. This isn't because they're related, it's respect."
One woman wrote: "So why they call her princess? Because it's a sign of respect!! Even Queen's account calls her princess."
Another simply added: "That's Princess Charlotte to you."
But others couldn't believe the comments, pointing out that she's their niece and probably don't use title when chatting to her.
One wrote: "Get a life and get down off your high horse."
Another added: "No that's Princess Charlotte to YOU and ME. NOT to her Uncle and Aunt. Let that sink in. Meghan is Charlotte's aunt!"
But the majority of people simply didn't care about the smaller details and just loved the couple's message.
The new photos of Charlotte were taken at Kensington Palace and the family’s Norfolk home of Anmer Hall last month.
