Prince William once again updated royal fans and the media on how Kate Middleton and the couple's children are doing as his wife continues preventive treatment for cancer.

On Friday, May 10, when the Prince visited St. Mary's Community Hospital in the Isles of Scilly, hospital administrator Tracy Smith asked Prince William, "How is Princess Kate doing?"

"She's fine, thank you," Prince William replied, according to a video shared by Sky News.

"It's lovely, and the children?" Smith asked. Smith asked, referring to Prince George, Princess Charlotte, and Prince Louis.

"The children are very jealous that I am here and that they are not here too," William replied.

The Prince of Wales spent his first night away from his wife to fulfill his royal duties, including a visit to St. Marys Community Hospital, since Middleton announced he had been diagnosed with cancer following scheduled abdominal surgery in January.

Not long ago, during a visit to James Place Newcastle (a charity established by the Prince of Wales that provides support and assistance to men in suicidal thoughts and crisis situations), Prince William was asked by one member of the public who asked the Prince, "How are your wife and children?"

"All doing well, thank you," Prince William replied. Yes, everyone is doing well."

"I mean, obviously Catherine..." The onlookers continued.

"Everyone is fine, thank you," the prince insisted.

Prince William provided a brief but positive update on his wife's health and well-being, but behind the scenes, the prince and princess are reportedly "raising hell."

Designer Amaia Arrieta, who has been responsible for some of Prince George, Princess Charlotte, and Prince Louis' most striking looks over the years, recently told The Telegraph, " I think they are having a hell of a time."

"I hope they come back," Arrieta continued. 'It's really a personal thing.'

While her husband has returned to his royal duties in the public eye, Middleton is away from the spotlight as he continues to undergo preventive chemotherapy for an unspecified type of cancer.

On Friday, May 3, The Times of London reported that the Princess of Wales is "expected to take some time off from official duties" and added that Middleton may be "willing" to attend public events "if she feels able".

A Kensington Palace spokesman explained that "any first public event" that the Princess of Wales attends "does not necessarily mean a return to her regular public schedule."
