Prince Louis's very cheeky stunt at Princess Kate's carol concert

Prince Louis was pictured playing a very cheeky stunt at the Princess of Wales’s Christmas carol concert last year.

The young royal, who was five at the time, was spotted alongside his two older siblings supporting their mum at the annual festive event.

Princess Kate, who is also mum to Prince George, 11, and Princess Charlotte, nine, looked delighted at being joined at the special event by her husband and their three adorable children.

Being up to his mischievous nature, Louis didn’t disappoint fans when it came to putting on a very cheeky display as he was spotted blowing out his sister’s candle as the family walked outside Westminster Abbey.

Appearing amused by her little brother, Charlotte – Kate and William’s only daughter – erupted into a fit of laughter.

Last year’s service was focused on a cause close to Princess Kate’s heart, after she had launched the Shaping Us campaign at the start of the year.

Despite her cancer diagnosis earlier this year – and having completed her treatment back in September – Kate’s annual festive service is set to take place at Westminster Abbey next week.

Much like last year, George, Charlotte and Louis are all expected to attend the service – as is their dad Prince William.

Although it will take place next week, the service will not be televised until Christmas Eve.
