Prince Louis cheekily blows out sister Charlotte’s candle at Kate’s Christmas carol concert, leaving his royal sibling in stitches

Prince Louis cheekily blew out his sister’s candle at Kate’s annual Christmas concert, leaving his royal siblings in stitches.

The cheeky five-year-old prince watched as his mother, the Princess of Wales, hosted a special festive service in Westminster Abbey today.

Princess Charlotte of Wales, Prince Louis of Wales and Prince George of Wales sent letters to Santa ahead of the Together at Christmas service.

But after the service, the mischievous royal blew out Charlotte’s candle as Kate laughed.

Prince Louis wore a plaid shirt and a smart navy coat, while Princess Charlotte wore a maroon jacket paired with polished black shoes. Prince George looked dapper in a white striped shirt, black jacket and tie.

However, this isn’t the first time Wales’ youngest child has stolen the show.

The fourth in line to the throne has become the center of attention at royal outings on several occasions.

When he took part in this year’s Pick of the Banner, the young royal stared at him as he covered his nose and mouth, considered disgusting, after smelling horse poop.

During his coronation, Prince Louis once again melted hearts at Westminster Abbey when he was spotted cheering for his grandfather, King Charles, exclaiming: “Yessss, King!” Yessss, king,” lip-reading expert Jacqui Press told Femail at the time.

Although the royal did not attend the coronation concert as it was time for him to go to bed, that did not stop him from attracting attention online as fans of The Firm wondered where he was.

Just days after the big event, he took the helm of a JCB excavator, sitting on Prince William’s lap and moving the mechanical arm.
