Oops! Can You Spot the Candid (and Relatable!) Slip-Up in the New Photo of Prince Louis?

Prince Louis may be a baby royal, but that doesn’t make him any less relatable.

On Monday, Kate Middleton and Prince William released three new photos of their little boy, showing off his adorable chubby cheeks and new teeth, ahead of his first birthday on April 23.

While some would assume that being a royal, regardless of age, is associated with poise and perfection, Louis proves in these new photos that there’s always time for some fun in the grass — even if that means getting dirty and being caught in the action!

As he was captured playing outside, Louis’ red sweater and navy pants became covered in grass. Still, that didn’t stop Kate and William’s youngest child from enjoying the moment as he showed off his giant smile and blonde locks, which were combed to the side.

In the sweet shots, which were taken by mom Kate earlier this month at their country home in Norfolk, Anmer Hall, Louis looks like a perfect combination of older siblings Prince George, 5, and Princess Charlotte, who turns 4 on May 2.

His style also mirrored that of his big brother’s. Besides the snaps showing Louis in his red sweater, the little royal also wore a blue sweater from Trotters featuring a puppy — recalling the striped whale sweater that George wore in the portraits released in honor of his third birthday in 2016.

Louis’ cheerful demeanor in the images is typical of the little royal, according to a source close to the family.

“He really is the most cheerful, smiley little boy,” the source told PEOPLE. “He’s always so happy and content.”

Keeping with tradition, Kate got behind the camera to take the sweet photos. The royal mom, who studied art history at the University of St. Andrews, is a keen photographer and regularly shares photos she’s taken of her royal children.

From birthday shots to first day of school moments, Kate can usually be found behind the camera capturing her family’s special memories.

Kate, 37, was behind the first official portraits of Louis, released just two weeks after his birth. A solo shot of Louis in a cozy white outfit was taken on April 26, just three days after his birth. And the little prince is wide awake in his first-ever portrait.

Another picture shows the early bond between Prince Louis and Princess Charlotte. Taken on May 2 (Charlotte’s third birthday), the proud big sister cradles Louis in her lap and places a sweet kiss on her sleeping sibling’s forehead.

Both photos were taken by Kate at the family’s home at Kensington Palace.

Royal fans last saw Prince Louis making his debut in the family’s Christmas card. The little prince looks directly at the camera while cuddled in Kate’s arms for the holiday portrait, taken in early fall at Anmer Hall.
