Prince George, Princess Charlotte and Prince Louis mark major milestone which hints at 'growing maturity'

George, 10, Charlotte, nine, and Louis, six, captioned the photograph themselves, writing a sweet and loving caption in their first-ever social media post.

The trio wrote: "We love you, Papa. Happy Father’s Day. G, C & L."

Writing in a column for MailOnline, Rebecca English said: "They simply wanted to show their love for William on a special day after what has undoubtedly been a difficult time for them all.

"The message does, however, mark the first time the children have been given such a platform to make a public statement like this to a global audience, and is a sign of their growing maturity as young royals."

William and Kate often address their fans directly by writing social media posts and leave a "W" or a "C" to make this clear to royal fans.

The photograph was signed "The Princess of Wales, 2024", to make it known that the picture was taken by Kate.

Kensington Palace confirmed that the new photograph was taken by The Princess of Wales in Norfolk last month.

William and Kate have a home in Norfolk called Anmer Hall, where they often spend the school holidays with their children.

This social media post comes just a few hours after the Prince of Wales posted a Father's Day message to King Charles.

William wrote: "Happy Father’s Day, Pa. W", alongside a photograph from 1982 of the young prince playing football with his father.

The photograph was taken on June 12, just three months before Prince Harry, King Charles's younger son, was born.

The Prince and Princess of Wales attended Trooping the Colour on Saturday with their three children, in what was a rainy but hugely exciting day.

It marked Kate's return to the public eye after spending several months undergoing chemotherapy, which she is set to continue.

The Princess of Wales looked incredible in a white and black Jenny Packham dress and a Philip Treacy hat.
