Prince William's son Prince Louis offered viewers a bit of comedy relief amid the serious events of the coronation as he was spotted looking 'bored'.

The new King and Queen of England appeared in front of the public to offer a wave from the balcony of Buckingham Palace in London, where they were joined by relatives including Prince William, his wife Kate Middleton, and their three children.

Coming after the King's official coronation at Westminster Abbey, the scene was one that will go down in history, marking the first appearance of a new King as he presented himself to the world.

But at five years old, it seems Louis wasn't really that impressed with the proceedings.

The youngster was spotted banging on the edge of the balcony and waving his hands around - gestures viewers couldn't help but attribute to his boredom during the long day.

"Prince Louis appears to be getting slightly bored with all this," one wrote, while another joked: "I’m only here for Prince Louis’ expressions."

The balcony wasn't the first time Louis was spotted looking bored at the coronation, with another Twitter user sharing a snap of him sat in Westminster Abbey and opening his mouth in what looked to be a huge yawn.

"I’m not watching the coronation, but this photo just popped up on The Age with Prince Louis looking bored as bats**t," they wrote.

Louis didn't seem to stick around for the whole event at Westminster as he was noticeably absent when the coronation reached the 90-minute mark.

However, he returned just in time to join his family in singing the National Anthem.

The young royal was given a front-row seat alongside his siblings in Westminster Abbey after being driven through the crowds gathered in London to celebrate King Charles.

Louis at least seemed relatively excited to see so many new faces, as he was seen peering out of the car window and giving a wave to onlookers as they drove past.

His brother, Prince George, arrived at the event separately from the rest of his family as he acted as a page for King Charles and helped carry the train of his robe down the aisle at Westminster.

Louis has a bit of a history of entertaining fans watching royal events, as at the late Queen's Platinum Jubilee celebrations last year he pulled faces at the crowd while watching the flypast from the Buckingham Palace balcony.
