Just when you thought Prince George and Princess Charlotte couldn't get any cuter, this happens.
The mini-royals were snapped at the wedding of close family friend, Sophie Carter, on Saturday, and much like Harry and Meghan's nuptials in May, the two little tykes caught the eyes (and hearts) of everyone around the world.
The images show George having a grand old time laughing and jumping while sporting the cutest white shirt, white tights and blue shorts.
Meanwhile Charlotte kept herself a little more composed, being pictured waiting patiently with Duchess Catherine. We can almost imagine her tutting at big brother George's excitable displays!
The siblings could almost be considered professionals within bridal parties. Along with Harry and Meghan's big day in May, they were also page boy and bridesmaid at aunt Pippa Middleton's wedding last year.
Prince George has made a name for himself already as an animated character. Last week, his dad Prince William revealed his five-year-old son's latest obsession was dinosaurs, and he couldn't stop talking about them!
During a visit to the Acorn Children's Hospice, Prince William told a group of young children, "George is obsessed with dinosaurs. We've been learning all about them."
Charlotte also has a cheeky side. At little brother Louis' christening in July, the three-year-old was heard telling paparazzi, "You're not coming". Bless.
It's clear the Princess is never far from Kate's side, often being photographed in her arms or holding her hand.
And much like her mum, she dotes on her little brother - in the official portraits from Louis' christening Charlotte is seen helping out as much as she can.
Kate and Wills' tiny tots have been growing up in front of our very eyes, with George starting school at Thomas's Battersea last year. Charlotte will start in 2019.
It remains to be seen if 5-month-old Louis will take after his brother and sister in the cheekiness stakes, but either way, we're confident he's going to steal our hearts time and time again - much like his older siblings!
