Princess Kate's heartwarming reaction to being asked if she's the Queen by brave boy, 10 – watch

The Princess of Wales had the most heartwarming reaction after she was asked if she was "the Queen" during a visit to a children's hospital in London. 

Kate, 44, met 10-year-old cardiac patient Ejran during a visit to the Evelina London Children's Hospital near Westminster on Tuesday – and he soon had some questions for her. 

Kate was asked: "Are you the Queen?" before beaming at Ejran and explaining: "No, I am the Princess of Wales."

She added: "It's very nice to meet you, I've come to see the amazing work that's going on here and see very brave children, like yourself."

Ejran, who has been in hospital for a month, gave Kate a thumbs-up afterwards, saying the encounter had been "amazing" and that he wants to meet King Charles next.

She was also told he had written a poem about Shrek and asked him to send her a copy so she could write back to him in the future. 

The Princess, who will one day be Queen when her husband Prince William becomes King,  later accepted a bouquet from Amelie, five, before departing.

She was wearing a bracelet which appeared to be made from string, made for her by her daughter Princess Charlotte when she undertook her recent Three Peaks Challenge.

The future Queen sat on the bed of the little boy, who was being discharged from hospital on Tuesday following treatment since the start of the year for a rare pulmonary vein condition after suffering a cardiac arrest.

The princess told the couple: "It’s amazing how children cope,” and added later, "I bet you’re desperate to get home?"

The reason behind Kate's hospital visit 

Evelina London is expanding its services to meet increasing demand, and plans are underway for a new hospital building next to the existing site, expected to open in the early 2030s.

A key part of Evelina’s expansion is their ongoing work with cancer specialist hospital The Royal Marsden, along with the major teaching institution St George’s Hospital, to move specialist cancer and blood and marrow transplant services for children in south London and southeast England into the future Children’s Cancer Principal Treatment Centre, housed in Evelina’s new building.

Kate also met a mother and her baby daughter, and chatted to a teenager who had problems with her pacemaker that left her passing out.

Before leaving, Kate held informal chats with the medical team working on creating the cancer specialist centre and met parents also providing input.
