Whether he's pulling faces or yelling in delight, royal fans can't seem to get enough of the youngster and his cheeky antics. Despite being one of the youngest royals, Louis has definitely earned his place as .
From his cheeky faces at the Queen's Platinum Jubilee to his inherently playful nature at his mum's Christmas Carol service, here the Express takes a look back at some of Louis' cheekiest moments.

The young prince joined his family at last year's Christmas Carol service in London - which is hosted by his mum Princess Kate. Although he appeared mostly on his best behaviour, Louis did delight fans with an array of cheeky faces during his appearance. While seeming to talk about the soloists from the Royal Ballet who performed during the service, Kate said that she had enlisted Louis to keep it a surprise for his sister - and that he did an excellent job at keeping to his word. Speaking to Paloma Faith, she said that Louis agreed, saying: "He has kept the secret for, what, nearly two weeks now."

Just as he did in December 2024, at Westminster Abbey the previous year. Although his siblings had attended before, it was Louis's first time attending the annual event. As the family-of-five stepped out, Louis couldn't help but let his cheeky side out at one given opportunity. The then-five-year-old was spotted trying to blow out his sister's candle as she stood next to him. Charlotte, however, showed that she was used to her brother's cheeky antics as she just laughed at what he was doing.

this year opting to spend the annual holiday in Norfolk. Walking hand-in-hand with his mum Kate, Louis - then aged four - appeared on his best behaviour - but not without pulling a few sweet, yet cheeky faces to onlookers. This appearance also shocked fans who pointed out that Prince Louis is "growing up fast" - prompting them to think he will likely be tall as an adult. Louis was also spotted cheekily poking his tongue out at onlookers. " data-has-syndication-rights="1" data-portal-copyright="GETTY" data-licensor-name="GETTY" />
