Prince William Celebrates Kate Middleton's 'Amazing' 43rd Birthday
Prince William shares the tradition of love with his wife, Princess Kate Middletonas he turns 43 years old.
“To an unbelievable wife and mother. The strength you have shown in the past year has been amazing,” wrote William, 42, alongside a new photo of Kate shared on social media on Thursday, January 9. “George, Charlotte, Louis and I are so proud of you. Happy Birthday, Catherine. We love you. W.”
William's sweet message for his wife comes after Kate was diagnosed with an undiagnosed cancer last year. In March 2024, Kate shared, “In January, I had major abdominal surgery in London and at the time my condition was thought to be cancer-free.”
“The operation was successful, but the tests after the operation revealed that cancer was present. So my medical team advised me that I should do preventive chemotherapy, and now I am in the first phase of that treatment,” he continued.
Kate finished her chemotherapy in September and has started back to work. William confirmed in November that Kate would “do more” in 2025.
The couple, who share sons Prince George, 11, and Prince Louis, 6, and daughter Princess Charlotte, 9, married in April 2011.
Last year, William reflected on his difficult year behind Kate and his father, King Charles IIIthey are being treated for cancer.
“It's probably been the hardest year of my life,” said William at the Earthshot Prize ceremony in November. “So, trying to get through everything else and keep everything on track was really difficult.”
In December, Kate held her annual “Together for Christmas” concert and spoke about her health battle. “I didn't know that this year would be the year I just had,” he told the singer Paloma Faith. “Unplanned. But, I think a lot of people this year had such a hard time.”
On December 25, the Princess of Wales opened up about her battle with cancer while addressing royal fans following the Christmas Day service at Sandringham.
“The number of people who wrote this year is amazing and I think that cancer affects many families,” said Kate, in photos obtained by the. Daily Mail.
While speaking to a fan who works in a cancer unit, Kate continued, “People like you do all the hard work out there. Thank you very much.”
After a woman told Kate, “We're all following you, don't you forget that,” the princess replied with a smile, “Thank you very much, [that’s] great grace.”
