The Prince and Princess of Wales were every inch the doting parents as they were joined by their three children for Kate’s Christmas carol concert this evening.

Prince George, 12, was on hand as the eldest brother, while Princess Charlotte, 10, and Prince Louis, seven, followed in suit.

The whole family was sleek in navy and green, as the boys wore smart suits while Charlotte was adorable in a blue dress with a white collar –  a perfect complement to her mother’s emerald winter coat.

Kate, 43, beamed proudly at her children, leading them towards Westminster Abbey as they admired the festive light decorations ahead of the service this evening.

Elsewhere William, 43, looked to enjoy a sweet conversation with his youngest son Louis, as they read messages on the Kindness Tree tonight.

The siblings also got in on the festive action as they signed their names on a sweet red paper chain which adorned the fir.

When inside, Louis once again had his parents’ attention as the Princess of Wales helped him balance a candle while holding onto the order of service as well.

Tonight’s carol service will feature a host of celebrities from Kate Winslet to Katie Melua as the Princess will bring together 1,600 guests to celebrate ‘the power of reaching out’.

Prince William, Winslet and actor Chiwetel Ejiofor will all give readings at the event which will recognise community stalwarts and honour ‘love in all its forms’.

Celebrity chef Dame Mary Berry, who has created a Christmas wreath on display in the abbey, will also be among the guests alongside leading sportswomen.

Melua, Fisherman’s Friends and Griff will perform on a roster also featuring Ted Lasso actress Hannah Waddingham and Dan Smith from pop rock band Bastille.

William and Kate’s children – Prince George, 12, Princess Charlotte, ten, and Prince Louis, seven – could also be present, as they were last year, alongside other royals.

The service will recognise individuals from across the UK who may have dedicated or volunteered their time to be present with others, led initiatives that bring people in their community together, or offered a helping hand to those around them.

Among those invited is schoolgirl Madison Reed, who last year raised more than £1,360 for the Archie Foundation by Highland dancing in 26 locations across Scotland, each beginning with a different letter of the alphabet.

She raised the funds for the charity, which supports sick children receiving medical care in north-east Scotland, along with their families.

In a letter that will be available to all guests, the princess has praised community stalwarts invited to the service, telling them they are making an ‘extraordinary difference to the lives of others’.
