Prince Louis has a knack for bringing levity to his royal appearances.

Part of the young boy’s charm is his lack of self-consciousness.

Even when the eyes of the world are on him, Louis is focused on his own experience.

Louis and Charles have a close relationship.

After a tedious day, Louis lifted Charles' spirits just by being there.

“[Charles] was sitting on the throne looking glum,” a source informedExpress.

“His eyes lit up and he said, ‘Hello, Louis.

I didn’t see you there.’

You could see how much he adored the little boy,” the source added.

With his mood boosted, Charles took the opportunity to bond with Louis over the royal artifacts.

“He explained everything to him and pointed out the different gems.

In that snapshot the two of them seemed completely entranced,” said the source.

Louis has a proven track record for bringing out Charles' playful side.

They have a special bond."
