Prince Louis joins the Royal family for his first Easter church service

King Charles leaves St George's Chapel, Windsor Castle, after attending the first Easter Sunday service of his reign.

The youngest child of Prince William and Princess Catherine made his debut public Easter appearance this weekend, joining his family at St Georges Chapel.

The 4-year-old Prince Louis joined his parents and older siblings, Prince George, 9, and Princess Charlotte, 7, at the royal family's traditional Easter church outing on Sunday (local time) - the first time the youngest prince had publicly joined the family outing, People reported.

The two older children made their debut in 2022.

All three children, as well as Mum and Dad, were wearing blue, but while older brother Prince George wore a suit and tie, Louis was dressed in shorts, knee socks, a blazer and tie with a bicycle print.

Traditionally, aristocratic boys wear shorts - even in cold weather - until they are about eight.

Prince George did the same until recent years.

He was following the footsteps of his father Prince William and uncle Prince Harry, who also wore shorts as youngsters.

Prince Louis made his official debut at the royal family church service on the Christmas morning in 2022.

Prince William and Kate, Princess of Wales with their children Prince George, left, Princess Charlotte and Prince Louis attend the Easter Mattins Service at St George's Chapel at Windsor Castle in Windsor, England.

While he was reported to have attended the previous year, Covid restrictions meant the family could not walk to the service and greet members of the public.

During his Christmas outing, Prince Louis was once again the centre of attention as he was pictured dragging his mother's arm during the walk.

The young royal's antics even stole the show at Queen Elizabeth's Jubilee celebrations in June, 2022, when he pulled faces while standing on the Buckingham Palace balcony, as a flypast took place.

Also, during the late Queen's Jubilee pageant, footage went viral of Prince William and Kate's youngest child as he pulled faces and put his hand across his mum's face during festivities.
