Prince Louis, Prince George and Princess Charlotte stole the show at King Charles III’s coronation ceremony — but they weren’t the only grandkids to make an entrance.

Princess Margaret’s grandson Samuel Chatto attended the historic event — and he came in hot.

The son of Lady Sarah Chatto and her husband Daniel arrived at Westminster Abbey in a formal outfit complete with a burgundy tie. He was also photographed with his well-dressed father after the service.

Samuel, 26, is 29th in line to the thrown. His mother is the only daughter of the late Princess Margaret and Antony Armstrong-Jones.

Margaret was Queen Elizabeth’s sister, making Lady Sarah the late monarch’s niece and King Charles’ cousin.

After Margaret died in 2002, Queen Elizabeth became a “surrogate mother” to Lady Sarah, with the pair sharing a close bond.

Sarah has worked as a painter under the professional name Sarah Armstrong-Jones and exhibited at many galleries, including The Redfern Gallery in London.

Her husband Daniel is also an artist, with the couple passing on their creativity to strapping son Samuel, who also exhibits an artistic touch.

Samuel attended Eton College before attending the University of Edinburgh where he studied History of Art and trained to be a yoga teacher.

He went on to work in the creative industry, working at an art market after graduation before becoming a craftsman, and eventually opening his own ceramics studio.

Samuel has shared multiple photos of himself in working away in his studio on Instagram, where he has become a royal heartthrob.

“You seem to be quite talented. And might I add that you are also quite handsome and charming,” one admirer swooned.

“My husband!” another wishfully declared.

It’s currently unclear whether Samuel is single.

While the Chattos aren’t part of the core working royals, they often attend major royal affairs such as Queen Elizabeth II’s funeral, Royal Ascot, and the Platinum Jubilee celebrations.

Samuel also has a younger brother, Arthur, 24.

Like his big brother, Arthur also graduated from the University of Edinburgh, but he hasn’t followed his other family members into the art world.

Instead, Arthur has worked as a personal trainer and he is currently serving with the Royal Marines.
