Princess Kate has plenty to celebrate this year as she marks her 43rd birthday on Jan. 9. After announcing she'd completed chemotherapy in September, the royal went on to make more regular appearances over the holiday season, and after having to go through abdominal surgery last January, it seems the royal is set to have more of a normal birthday this year. In a break from tradition, Prince William penned a touching personal note on their joint Instagram account to celebrate the occasion.
Normally, the couple share a photo of the royal with a general message thanking well-wishers for their birthday messages, but for 2025, the Prince of Wales himself wrote the caption as he shared a gorgeous black-and-white snapshot of his wife.
