Prince William assured royal followers during an outing on Tuesday that all is well at home.

During a surprise walkabout after an engagement in Newcastle upon Tyne, the Prince of Wales spoke with a concerned fan who asked how he and his family were doing.

Do you mind if I ask how you and the children are? a woman in a Union Jack hat and cape asked the prince.

All doing well thank you. Yes, were doing well, William answered in a clip captured by the Daily Mail, as the woman asked about Williams wife, Kate Middleton , the Princess of Wales.

Were all doing well, William reiterated, before complimenting the womans companion on part of her patriotic outfit.

It was the first update William has shared since Kate announced her cancer diagnosis in a March video, following months of speculation about her health.

In January, I underwent major abdominal surgery in London and at the time, it was thought that my condition was noncancerous, Kate said in the video, adding that her surgery was successful.

However, tests after the operation found cancer had been present, she explained. My medical team therefore advised that I should undergo a course of preventative chemotherapy, and I am now in the early stages of that treatment.
