Prince Louis Arthur Charles of Wales is celebrating his eighth birthday today. The Prince and Princess of Wales welcomed their third child into the world on this day in 2018.

Despite being one of the youngest members of the Royal Family, Prince George and Princess Charlotte’s little brother has definitely earned his place as one of the public’s favourite members of the Firm. Whether he’s pulling faces or yelling in delight, royal fans can’t seem to get enough of Louis and his cheeky antics.

From his cheeky faces at the late Queen’s Platinum Jubilee in 2022, to his inherently playful nature at his mum’s Christmas Carol service each December, here The Express takes a look back at 13 of Louis’ cheekiest moments.

Easter Sunday Service

Prince Louis and his siblings made their first public appearance of 2026 at the Easter Sunday service earlier this month. The young royal, closely followed by his big sister, waved at delighted royal fans waiting outside the church where the service was held in Windsor.

Kate’s Christmas Carol Service in 2025

Princess Catherine was seen keeping an eye on her youngest son as the family sat front row at her annual Christmas Carol service in December 2025. Louis can be smiling at his mum – with the young royal also joined by his doting older brother and sister.

Christmas Day Walkabout

The young royal made an appearance during the Royal Family’s Christmas Day walk in 2024. Louis, alongside his two older siblings, got to engage with members of the public, who lined the walk to St Mary Magdalene Church in Sandringham. During the event, Louis drew laughter as he smashed a Terry’s Chocolate Orange on the floor during a church service. According to The Sun, Reverend Canon Dr Paul Rhys Williams told Louis that you have to tap it and unwrap it.

Royal fans gathered outside the church, listening to the service via speakers, then heard him tell Prince Louis: “Just drop it.”

Kate’s Christmas Day Service in 2023

Prince Louis attended the Princess of Wales’s Christmas carol concert at Westminster Abbey in 2023 – just as he has in previous years and years since. 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, clearly used to her brother’s cheeky antics, laughed at what he was doing.

Royal International Air Tattoo

Prince Louis – joined by his siblings – began his school holidays in July 2023 with a visit to Royal International Air Tattoo at RAF Fairford. Amusing fans, Louis was seen cheekily signalled whilst he was seen sitting on one vehicle.

The Air Tattoo is the world’s largest military air show, featuring over 250 aircraft from 25 nations and attracting over 200,00 spectators over the weekend. The event is staged in support of the RAF Charitable Trust, which aims to support the RAF and encourage interest in the aviation industry among young people.
