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 carol concert, which has left his royal siblings in stitches.

The cheeky prince, five, watched his mother, the Princess of Wales, host the special festive service at Westminster Abbey today. 

Princess Charlotte of Wales, Prince Louis of Wales and Prince George of Wales posted letters to Santa before The 'Together At Christmas' Carol Service 

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

Prince Louis was dressed in a chequered shirt with a smart navy coat, whilst Princess Charlotte donned a maroon jacket, paired with polished black shoes. Whereas Prince George was looked dapper in a white striped shirt, black blazer and a tie. 

However, this is not the first time the youngest of the Wales's children has stolen the show. 

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

When he took part in Trooping the Colour this year, the young royal had all eyes on him as he covered his nose and mouth in what is thought to be disgust, after he caught a whiff of horse poo.

On the Coronation, Prince Louis melted hearts once again at Westminster Abbey as he was spotted cheering for his grandfather, King Charles, exclaiming: 'Yaaaay Say king. Yaaaay king,' lip reading expert Jacqui Press told Femail at the time.

Although, the royal did not attend the Coronation concert as he was past his bedtime, this did not stop him gaining attention online as fans of The Firm wondered where he was. 

Just days after the big event, he then got behind the controls of a JCB digger, as he sat on Prince William's lap whilst he moved the mechanical arm.

Many may remember when he covered his ears and appeared to scream next to the late Queen on the balcony of Buckingham Palace, due to the planes flying past.
