The Palace also announced the details of Princess Charlotte’s Christening.
The very modern royal parents, the Duke and Duchess of Cambridge, shared a photo of their children Prince George and Princess Charlotte, in the early hours of Sunday morning Australian time.
They set social media aflutter hours before by posting a photo saying they would be posting a photo. So meta.
“We’ll be posting a very special photo of Prince George and his little sister Princess Charlotte on @instagram late tonight. Can’t wait to share it with you!” the caption read.
This is the first official photo of the baby since she left hospital 10 hours after she was born.
These gorgeous photos of George and Charlotte are just about the cutest things we've ever seen.
"We're delighted to share the first photo of Prince George with his little sister Princess Charlotte. #WelcomeToTheFamily," the caption reads.
"This photograph is the first of four official photographs being released today, taken by The Duchess of Cambridge in mid-May."
The photos were taken by the Duchess of Cambridge. (Has she been hiding some serious photography skills? Hope to see more of her work in the future.)
Kensington Palace shared photos from behind the scenes all day.
"The Duke and Duchess are extremely grateful for the wonderful messages they've received on the birth of Princess Charlotte. Mail sacks with congratulations from across the globe arrived at St James's Palace shortly after Princess Charlotte's arrival."
