The Crown's Josh O'Connor and More React to Kate Middleton’s Cancer Battle

Hollywood is sending their well wishes to Princess Kate Middleton after she shared her cancer diagnosis.

After weeks of speculation surrounding her well-being and whereabouts, the Princess of Wales shared her condition via a video message on Friday, March 22.

“In January, I underwent major abdominal surgery in London and at the time it was thought that my condition was non-cancerous,” Middleton, 42, said. “The surgery was successful, however, tests after the operation found cancer had been present. My medical team therefore advised that I should undergo a course of preventative chemotherapy, and I’m now in the early stages of that treatment.”

While Middleton said she is “getting stronger every day,” she said her family now needs “some time, space, and privacy while I complete my treatment.”

“My work has always brought me a deep sense of joy, and I look forward to being back when I’m able,” Middleton continued. “But for now, I must focus on making a full recovery.”

Although many celebrities shared their theories in recent weeks as to what was going on with Middleton, Jamie Lee Curtis took a more empathetic approach hours before the princess’ announcement.

“Can we please just STOP with this bullshit conspiracy theory?” she wrote via Instagram on March 22. “This is a human being with young children, and clearly some sort of a health issue. That is a private matter. Do we not have better things to do and more important things to think about and be concerned about than this? It’s a really low point in our society when there are SO MANY crucial issues that need our attention.”
