Kate Middleton reveals sweetest nickname for Prince Louis at his first royal engagement

Prince Louis may have missed out on the nighttime Coronation Concert on Sunday, but Prince Williamand Princess Kates younger son was more than ready for an action-packed day with the Scouts on Monday morning.

Five-year-old Louis, dressed in a striped polo top, shorts and for his first-ever royal engagement – and in one of the sweet interactions with mum Kate, his adorable nickname was revealed.

The tender moment took place as the Prince and Princess of Wales visited the 3rd Upton Scout Group in Slough with all three of their children, including Prince George and Princess Charlotte.

At one point, Princess Kate joined a group of children, including her own, to toast marshmallows over an open flame. As the royal mum-of-three helped Prince Louis with the fun task, handing him a stick to discard, she could be heard saying: “Pop that in the fire, Lou Bug.”

Then, as a member of the group gave Lou Bug his very own s’more to eat, the Princess of Wales showed that she’s a hands-on mum, gently reminding the young Prince, “What do you say?” and he responded with a timid smile, “Thank you.”

In addition to assisting in the renovation of the Scout Hut, with such tasks as sanding and painting, the family also helped reset a path – and Prince Louis even had a chance to sit on his father Prince William’s lap as he drove an excavator.

In fact, one volunteer asked Louis: ‘“You might want to be a painter when you grow up?” The little Prince responded: “No, a fighter pilot.”

“Just like your father and grandfather!” the volunteer replied.

Scout leader Simon Carter told HELLO!: “[Prince Louis] was really excited. They all got presented with a Big Help Out badge at the end, so they all got a Scouts scarf… He was the one who ran away with the wheelbarrow. He was the one who was digging sand and getting stuck in and doing things.”
