Prince William celebrated Kate Middleton's birthday with an emotional message.

Prince William shared an emotional message on Instagram for his wife Kate Middleton's 43rd birthday, who successfully completed her cancer treatment. In his message, William emphasized his wife's struggle over the past year, saying, "The strength you have shown over the past year has been extraordinary."

Speaking on behalf of their three children, George (11), Charlotte (9), and Louis (6), William stated, "We are all proud of you." In his post, he also shared an unseen black-and-white photo of Kate, ending his message with, "We love you. W."

In the photo taken by photographer Matt Porteous, Kate poses for the camera with simple elegance. Wearing a white top, a black blazer, and a checked scarf, Kate's natural and happy appearance stands out.

The couple, who married in 2011, had a challenging year. Kate announced in January 2024 that she would step back from her duties for abdominal surgery. After rumors circulated during her prolonged absence, she shared her cancer diagnosis with the public in March. In September 2024, she successfully completed her chemotherapy treatment and regained her health.

King Charles and Queen Camilla, who are also battling cancer, celebrated Kate's birthday with a message featuring a cake emoji. Following her treatment, Kate is gradually returning to royal duties and has been seen more frequently in public.
