Prince Louis adorable handwriting has warmed the hearts of fans this festive season as the young royal stole the show at his mother’s Christmas Carol Concert yesterday.

A long red paper chain decorated the tree outside Westminster Abbey yesterday, inscribed with hundreds of messages and names.

Among the names attached to the Kindness Tree, were Prince Louis, seven, Prince George, 12, and Princess Charlotte, ten.

But it was the handwriting of the youngest royal that melted the public’s hearts with his being the only one of the siblings not to use cursive.

Meanwhile, Kate’s fifth Together at Christmas service featured a host of celebrities from Kate Winslet to Katie Melua.

Yet despite the star-studded guest list, it was cheeky Prince Louis who stole the limelight at the carol service.

Last night Princess Catherine warmly greeted her children, putting her hands on their shoulders, after they added their ribbons to the tree.

Both George and Louis looked smart in dark suits and green ties with their hair combed to the side.

Fans were quick to compare a ‘smart and sophisticated’ Louis to his grandfather King Charles, pointing out he also likes double breasted suits.

Meanwhile others described the young prince as Catherine’s ‘mini me’, comparing photographs of the two at similar ages.

‘Prince Louis’ smile is just like his mum’s,’ one fan wrote to X, while a second wrote, ‘Prince Louis looks absolutely adorable with Princess Catherine.’

‘My heart melts every time I see moments like this from the Royal Family. This is truly one of the most beautiful captures such a sweet, tender moment in a single picture.’

Another added: ‘Prince Louis! He’s growing up so fast! Beautiful images of selfless motherhood!’

Princess Catherine’s own family, including her parents Michael and Carole Middleton, and her brother, James, were also in attendance at the event.

Meanwhile, Princesses Beatrice and Eugenie did not attend the carol service yesterday evening despite being personally invited by Princess Catherine.

It was previously reported that the princess reached out to Prince William’s cousins, asking them to attend the star-studded event alongside 1,600 other guests.

The invitation was understood to be a bid to help keep the Royal Family united and connected this Christmas amid the latest scandal surrounding their father Andrew.

While Beatrice, 37, and Eugenie, 35, were touched to have been asked, both had previous commitments and were unable to join other family members at the service.

In a post on social media, Eugenie said: ‘Wish Bea and I could have been celebrating tonight with our family.

‘Wishing @princeandprincessofwales such a special evening at her incredible carol service. What an amazing message of love and hope.’

Eugenie wrote the message next to a snap of a program from the service organised by Princess Catherine nestled on a branch of a Christmas tree.

The hour-long service celebrated ‘the power of reaching out’ – however singer Hannah Waddingham pulled out at the last minute due to issues with her voice.

William, Winslet and actor Chiwetel Ejiofor all gave readings during 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, was also among the guests alongside leading sportswomen.

The Princess arrived shortly after 4pm ahead of her family for last-minute checks and to meet some of the guests, followed by Winslet – festive in red – and Ejiofor.

Meanwhile, guests were greeted by a festive display created by horticulturist Jamie Butterworth based on the importance of nature in our lives.

Melua, Fisherman’s Friends and Griff performed on a roster also featuring Dan Smith from pop rock band Bastille.

The singer Zak Abel performed another carol – Silent Night – in Ms Waddington’s place, although this was not reflected in the order of service due to the late change.

In a letter that was 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’.

She also extols the virtues of the Christmas period that reminds us ‘how deeply our lives are woven together’, adding that despite life feeling ‘fragmented or uncertain’ at times, the festive season ‘invites us to remember the power of reaching out to one another’.

In her letter, Kate says: ‘This carol service offers a moment of collective togetherness, a chance to celebrate the spirit of community and service, and to honour the visible and invisible bonds that unite us all.

‘The time, care and compassion you give, often quietly and unspoken, and without any expectation or recognition, make an extraordinary difference to the lives of others.’

Some 15 community carol services, held in places including the Coronation Street Visitor Centre, an arts centre in Newbury and a community farm in Gwent, are also set to take place across the UK with the same love and togetherness theme and those guests will also receive Kate’s letter.

The full list of locations for the community services included Armagh, Berkshire, Derbyshire, Dumfries, Dyfed, East Riding, Gwent, Greater Manchester, Isle of Wight, Lanarkshire, Nottinghamshire, Renfrewshire & Ayrshire, Suffolk, Wiltshire and Worcestershire.

These services were hosted by lord-lieutenants and supported by The Royal Foundation.
