Prince Louis showed off his close relationship with his Grandpa, the king, during his first public engagement when he was splashed with white paint.
The young royal, five, had been helping paint an outdoor planter with the 3rd Upton Scouts Hut in Slough to help out renovate the building as part of the Big Help Out.
During the hard work however he was splashed with a little of the white paint which ended up in his hair.
Rather than being unhappy however he quipped he has white hair, before hilariously adding: “just like Grandpa.”
The youngster joined his parents the Prince and Princess of Wales as well as his siblings Prince George and Princess Charlotte for the third day of celebrations last weekend.
They all took part in the Big Help Out at 3rd Upton Scouts Hut in Slough to assist in renovating and improving the building.
After noticing the splash of white, Charlotte told her brother: "You've got paint in your hair! Louis, look at me! Look at me!"
They helped with tasks including resetting a path, digging a new soakaway, sanding and revarnishing the front door, adding planters to the front of the building and adding a mural to create a lasting legacy of the Big Help Out’s work. Kate has been joint president of the Scouts since 2020.
Louis, wearing his trademark shorts, sat in his father's lap as William operated a digger and moved the mechanical arm to grab a bucket full of soil before dumping it on a spoil heap.
It came after seeing big brother, George, nine, have a go and telling his mother: ‘I want to go in with him!’.
The children set to work straight away with the Scouts with Charlotte and Louis helping to paint a planter and George joining his father with some drilling.
The two youngest children knelt down, grabbing brushes dripping with white masonry paint, obvious to the fact that they were getting it on their hair and bare legs.
Afterwards it was time for a little fun, with the children each given the chance to have a go at archery. Charlotte proved a natural, scoring a bullseye first time..
Little Louis, whose bow was a big as him, also showed he has inherited his parents’ sportiness, hitting the target as well.
He loved it so much that he kept on running back to pick up his arrows and and having another go, hitting the target several times.
George, to the rear, scored several direct hits himself before having a mini competition with his mother and father.
