The royal family are preparing for one of the biggest events in their summer calendar – Trooping the Colour.
The annual military parade, which marks the King's birthday, takes place on Saturday 15 June in London.
The King and Queen will be joined by members of the royal family for the momentous occasion, including the Prince and Princess of Wales and their three children - Prince George, ten, Princess Charlotte, nine, and Prince Louis, six.
It will mark Kate's first public appearance since starting preventative chemotherapy in late February following a cancer diagnosis, with the Princess writing in a personal message shared on Friday: "I'm looking forward to attending The King's Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet."
However, it's understood that the Princess' attendance at the parade should not be interpreted as a return to work or her resuming a full schedule of public engagements.
It's expected that her future appearances will be decided on a case-by-case basis, depending on how she is feeling nearer the time.
While Prince George has attended football matches with his father William in recent months, most recent being the FA Cup final between Manchester United and Man City in May, Princess Charlotte and Prince Louis' last public appearance was on Christmas Day 2023.
Mum Kate got behind the camera to take the official portraits of Charlotte and Louis to mark their respective birthdays in May and April.
HELLO!'s Royal Editor Emily Nash said of the royal children's appearance in her HELLO! Royal Club newsletter this week: "What has proved to be a very challenging year for the royals health-wise and amid the uncertainty of a General Election campaign, the presence of the young royals at events this Saturday will be crucial for The Firm."

Carriage procession
In recent years, the three Wales children have taken part in the carriage procession at Trooping the Colour, riding in a carriage with their mother Kate and step-grandmother Camilla.
On Saturday, the Princess will be joined by her three children in a carriage for the traditional procession to Trooping the Colour and later they will gather with other royals on Buckingham Palace’s balcony for the fly-past.
Royal children on the balcony
The Prince and Princess of Wales's children always delight royal watchers when they appear in public and they have often stolen the show with their royal cousins on the palace balcony during Trooping the Colour.
George's fascination with aircraft stems from a young age and the little prince made his debut at the royal event when he was just shy of his second birthday in 2015.
He was seen pointing and waving animatedly at the flypast in his father's arms to the enjoyment of then Prince Charles and Queen Elizabeth II.
Charlotte had already perfected her royal wave when she appeared on the palace balcony for the first time just after her first birthday in 2016.
Two years later, George and Charlotte amused the crowds with their antics with elder cousin, Savannah Phillips, as they pretended to conduct the military band.
And in 2019, one-year-old Prince Louis charmed the public, enthusiastically waving and pointing at the planes during the flypast. Relive the moment in the clip below...
