News that both King Charles III and Kate, Princess of Wales are undergoing hospital treatment is dominating UK front pages.
The Princess, 42, has now had "planned abdominal surgery" and will be in hospital for two weeks recovering.
The King, 75, is having an operation on an enlarged prostate - a common condition in older men - next week.
Updates on the royal hospitalisations were released less than two hours apart on Wednesday afternoon, overnight Wednesday Australian time.
It is unusual for such intimate details to be released on royals' health.
The Sun focused on Kate, saying: "Royals rocked by Kate op"
It said the royal family had been "rocked by a double health blow."
However it quoted a royal insider saying the Princesses condition is not related to cancer.
Apart from that, the papers have not offered any more insight into what could be wrong with Kate.
"Two weeks in hospital is longer than we would normally expect, but she doesn't have a normal life," Dr Zoe Williams told The Sun.
"She's the future queen so the doctors will be erring on the side of caution."
The paper even has an online form where readers can send wishes to Kate.
Meanwhile, The Daily Mail went with the dramatic headline "Let's pray that they're both OK" strapped with "Royal Health Bombshell".
It said that the pair were both having "serious medical treatment."
Columnist Richard Kay called the update on Kate "profoundly shocking," and said the double update "leaves the nation reeling".
"After the sadness of the late Queen's slow decline and death, the bulletin about Catherine has sent a collective shiver down the spine of royal fans. People are reeling," Kay said.
