During Prince Louis' first christening in 2018 at The Chapel Royal at St James' Palace, Catherine, Duchess of Cambridge was overheard telling the Arch Bishop of Canterbury that her youngest child was "very relaxed and peaceful" and she hoped he stayed that way.
But if Prince Louis' latest Platinum Jubilee antics are anything to go by, the duchess was unknowingly tempting fate as the four-year-old royal was anything but calm. His adorable and excitable behaviour truly stole the show during the weekend of celebrations
The fifth in line to the throne has a legion of royal fans, but which relative does he look the most like? We investigate below.
Of course the tiny royal will show some resemblance to Prince William, he is his father after all! But perhaps the likeness was more uncanny when Louis was merely a bub.
The Duke of Cambridge was christened at just six weeks old in a private ceremony in the Music Room of Buckingham Palace. As he sucked on his mother Prince Diana's thumb, the baby prince looked peaceful and serene, just like sleeping Louis, 36 years later.
Now that he's older, Louis has darker hair and slightly different facial features to his father.
We can see where Louis, George and Charlotte get their adorable chubby cheeks from! The Duchess of Cambridge was just too cute as a child. As he's gotten older, we'd say Louis' facial features are looking even more like his mum as a youngster.
With his chubby cheeks and button nose, we think Louis looked almost identical to baby Prince George! But as he's grown into a toddler, Louis has developed darker hair and slightly different facial features to his older brother.
Swipe across to see if you can find a resemblance between baby Louis and baby Charlotte.
With an identical hair colour and alike facial features, we'd say little Louis looks pretty similar to Charlotte when she was his age. But will it stay that way as he grows older? Only time will tell.
While he isn't part of the main Cambridge clan, Michael Middleton is a name that keeps cropping up amongst royal fans as holding a keen similarity to his grandson, Louis. Do you see the resemblance?
As he and older siblings George and Charlotte headed off for their first day of their new school in September 2022, Prince Louis looked even more like Michael Middleton! What a cutie.
