Prince Louis is looking out for his dad.

On Monday, the 7-year-old was captured in a delightful moment as he groomed Prince William’s military attire during the festivities commemorating Victory in Europe Day at Buckingham Palace.

In addition to his adjustment, the little one also tugged at the yellow braided cord on his father’s jacket.

Louis was seated beside William, 42, to watch the military procession, with brother Prince George on his other side.

George, 11, sat next to Princess Charlotte, with the 10-year-old followed by mom Kate Middleton.

The Princess of Wales, 43, stunned in a magenta outfit and matching pillbox hat, while her three kids coordinated in black formalwear.

Louis was caught on camera sticking out his tongue, staring at the sky with a tired expression and revealing his missing front teeth.

Over the years, William and Kate’s youngest child has become best known for stealing the show at royal outings with silly faces.

Charlotte even made headlines for reprimanding her little brother over his viral antics at last year’s Trooping the Colour parade.

During the June 2024 festivities, the princess scolded Louis for dancing.

Charlotte has also called out George, reminding the future king to bow at Queen Elizabeth II’s funeral two years prior.

She and Louis, notably, both celebrated birthdays in the last month.

Louis marked his seventh year on April 23 with a new shot showing off his gap-toothed smile.

In Charlotte’s May 2 portrait, taken by Middleton, she sported a camouflage jacket and backpack while outdoors.

George is set to turn 12 on July 22.

Recently, William and Middleton, who established their family in 2013, marked their 14th wedding anniversary by embarking on a trip to the nation where they first met.

The duo first crossed paths in 2001 while attending the University of St. Andrews in Scotland.

They started dating the following year, getting engaged — and then married — in 2010 and 2011, respectively.
