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."
"Among messages of congratulations, The Duke and Duchess of Cambridge have received impressive hand-painted cards and group projects from schoolchildren and Brownie groups. Thank you to everyone who has taken time to make handmade gifts for Princess Charlotte - here are a few of them!
Earlier, the palace announced in a short statement to the press that Princess Charlotte will be christened on Sunday the 5th of July at St Mary Magdalene Church, Sandringham, near the Queens' favoured rural estate.
The private ceremony will be conducted by by The Archbishop of Canterbury, the Most Reverend Justin Welby, as the spiritual head of the Church of England. Archbishop Welby also conducted Prince George's Christening.
Traditionally, royal babies have been christened in the music room at Buckingham Palace. However, William and Kate broke that tradition when they had Prince George christened in the Chapel Royal at St James' palace.
