In news that will no doubt make for an emotional week for Duchess Catherine, her youngest daughter Princess Charlotte is about to hit a very special milestone that will mark the end of an exciting chapter.
Indeed four-year-old Charlotte, who started nursery in January 2018, will be preparing for something very big set to happen in September, and the countdown officially starts this week.
You guessed it - Princess Charlotte will have her last day at nursery this week, and will join her big brother Prince George at school in September.
After being a pupil at Wilcocks Nursery (located in Kensington) for over a year, the young royal will be sad to say goodbye.
But it won't be long before she's back into a whole new world of schooling - and we can't wait to see Charlotte in her new school uniform!
Last year, Kate shared a gorgeous picture of her daughter on her first day at the nursery.
Wearing a red coat with matching red buckled shoes, the adorable young Cambridge looked ready for action.
Since then, we can't believe how much she's grown up - especially after Kate released photos of the four-year-old on her birthday this year, revealing her to be looking more and more like a mini Kate-and-William by the day!
At Willcocks Nursery, Charlotte has partaken in a number of activities, including singing, cooking and learning about the prestigious school's ethos: "High standards, excellence and good manners".
It was confirmed by Kensington Palace earlier this year that young Charlotte would be joining her big brother at Thomas's Battersea on September 5 when it commences the new school year.
Charlotte is expected to wear the school uniform, the colours of which include navy and red.

In June, Charlotte put on a display that was revered by the masses when she attended the annual Trooping the Colour parade, where she stepped out on Buckingham Palace's balcony alongside her family.
The young royal was spotted peering out the window with her younger brother Prince Louis shortly before the balcony appearance, which caught the attention of the crowd in the best way possible.
Later on, she and George were seen gazing at the sky in wonder (and blocking their ears for good measure!) as the traditional flyover occurred.
How wonderful for the young royal!
