King’s cousin Sarah Chatto and her heartthrob son Arthur join royal family at Kate Middleton’s carol concert

Princess Margaret’s daughter Sarah Chatto and her hunky son Arthur joined the royal family at the Princess of Wales’ Together at Chrsitmas carol concert on Friday. 

Lady Sarah, 59, and Arthur, 24, were among the extended members of the Firm to support Kate Middleton at Westminster Abbey.

Looking regal in a white coat, Sarah, who was often described as the late queen’s ‘favourite niece’ wrapped up with a scarf as she walked alongside her husband Daniel.

Meanwhile, Arthur, a personal trainer who has won a legion of fans thanks to his shirtless Instagram snaps, looked smart in a red scarf a suit.

The mother-of-two is the only daughter of the late Princess Margaret and her former husband, Antony Armstrong-Jones, who passed away in 2017. 

The late Queen was described as a ‘surrogate mother’ to Margaret’s children and was particularly close to Lady Sarah, who is believed to have reminded her of her late sister.

Both her parents passed on their artistic eye to their children as Sarah, now a painter, and her brother David were taken around galleries in their youth.

Sarah went on to complete a foundation course at Camberwell School of Arts and Crafts, followed by a printed textiles course at Middlesex Polytechnic, paving the way for her training at the Royal Academy Schools.

Working as a painter under the professional name Sarah Armstrong-Jones, she has since exhibited at galleries including The Redfern Gallery in London.

Her wedding to Daniel Chatto in July 1994 was such a short, simple affair that chauffeurs were caught by surprise: the Queen, Prince Philip and Princess Diana waited at the City church of St Stephen’s Walbrook after the service for their cars to come back.

While the Chatto’s are not at the centre of the working royals, they have attended major royal events over the years, including the late Queen Elizabeth II’s funeral last September, Royal Ascot, Trooping the Colour, as well as the Platinum Jubilee celebrations.

Meanwhile, Lady Sarah’s eldest son Samuel – who attended Eton college before studying at the University of Edinburgh – was pictured alongside his equally smartly dressed father following the service.

The royal was brought up in Kensington, London. He studied History of Art at university and trained as a yoga teacher before settling on a career in the creative industry – just like his artist father.

Kate hosted her Together At Christmas event at Westminster Abbey and welcomed her family, members of the monarchy and inspiring individuals in celebration of those supporting children and families.

The Prince of Wales arrived with Prince George, Princess Charlotte and Prince Louis, after Kate travelled ahead to thank celebrities for agreeing to perform, including Oscar winner Jim Broadbent and singers Beverley Knight and Adam Lambert.

As they walked into the Abbey’s forecourt the royal children paused for a moment to post Christmas cards, in a special postbox, containing messages for children who might be struggling this Christmas, something open to all youngsters attending.

The young royals – George, 10, Charlotte, eight, and five-year-old Louis – were all smartly dressed while their mother wore a Chris Kerr coat.

Before the concert started Kate met celebrities in the Abbey’s stunning 16th century Lady Chapel, and chatting to Broadbent expressed her appreciation at him agreeing to read an extract from Letters From Father Christmas by Lord Of The Rings author JRR Tolkien.

She said: ‘Thank you for your time because I know the lead up to Christmas can be busy for people.’

Kate appeared to joke with multi-instrumentalist Collier, who has posted music tutorial videos on YouTube, about her daughter learning the piano and he quipped ‘many a plink and a plonk’.

She also walked around the Abbey before the event began, speaking to young people who have done inspiring activities.

Once inside, Kate stole the show as she led the royal family  and high-fived and spoke with children who have gone ‘above and beyond’ for charity.

Kate crouched down to chat to seven-year-old Oscar Burrow, from Lancaster, who raised more than £40,000 for Derian House Children’s Hospice in Chorley, Lancashire, by climbing 12 mountains at the age of six.

His mother Kimberley Burrow said afterwards: ‘She said she’d heard about what he’s done and he’s doing a fantastic job, and hopes what he’s doing will inspire other children to do amazing things.’

The princess was joined at her annual Christmas carol service by Prince William and children Prince George, Princess Charlotte and Prince Louis. 

The Royal children were seen stepping in to the event at Westminster Abbey – while five-year-old Prince Louis once again drew attention by blowing out his sister’s candle and chatting to a statue outside.

Kate walked around the Abbey before the concert started speaking to young people who have done inspiring activities.

She knelt down and spent time speaking with seven-year-old Oscar.

The princess placed her hand on a chair and the other in her lap as she discussed his impressive fundraising efforts, watched on by his smiling mother. 

She chatted to four scouts from the 3rd Upton Scout Group in Slough her family visited during the coronation celebration weekend, part of The Big Help Out event, helping to renovate their hut.

The princess told them: ‘It was really inspiring. Seriously, good job’. She then high-fived each scout in turn.

Kate, who was dressed all in white for the occasion, was pictured bending down to light Prince Louis’ candle with her own.

At one point she was seen placing a reassuring hand on his back as he appeared to clutch at her coat amidst the gravity of the evening. 

As she arrived at the concert, she was seen holding Princess Charlotte’s hand. 

Among the group of celebrities waiting to greet the family in the Abbey’s Lady Chapel were singers Beverley Knight and Adam Lambert, musician Jacob Collier and actor Jim Broadbent.

Catherine’s sister Pippa and husband James Matthews were also photographed arriving this afternoon, as were Lady Sarah Chatto and her husband Daniel Chatto.

The Princess herself unveiled a very special festive gift to guests at the concert – a rendition of Last Christmas played on John Lennon’s piano.

Before the concert started, Kate met celebrities in the Abbey’s stunning 16th century Lady Chapel, and chatting to Broadbent expressed her appreciation at him agreeing to read an extract from Letters From Father Christmas by Lord Of The Rings author JRR Tolkien.

She said: ‘Thank you for your time because I know the lead up to Christmas can be busy for people.’

Kate appeared to joke with multi-instrumentalist Collier, who has posted music tutorial videos on YouTube, about her daughter learning the piano and he quipped ‘many a plink and a plonk’.

The service began with the popular carol, Once In Royal David’s City, and the congregation also heard a duet by Beverley Knight and Adam Lambert who performed The Christmas Song, made famous by Nat King Cole.

William read the passage from the Gospel according to Luke that describes how Joseph and Mary travelled to Bethlehem to be registered and the birth of Jesus.

The Abbey echoed with the voices of its choir and the congregation singing a selection of carols including Silent Night, Holy Night and Joy To The World, as well as Hark! The Herald Angels Sing.

The historic building featured Christmas trees from Windsor Great Park donated by the King, which will be given to local communities after the service.

The event will be broadcast as part of Royal Carols: Together At Christmas, a special programme airing at 7.45pm on ITV1 and ITV X on Christmas Eve, featuring additional material including an introduction by Kate and films emphasising the importance of early childhood.

The broadcast will include contributions from Rio and Kate Ferdinand, Ugo Monye, Andrea and Virginia Bocelli and Dame Sheila Hancock.
