Kate Middleton and Prince William celebrated Valentine's Day by sharing a rare PDA photo on social media. The image, originally released in September 2024, shows the couple holding hands and sharing a kiss. The couple, who have been together for over 20 years, have typically been more reserved in public, but there is no royal protocol against PDA. The photo was part of a video announcing Kate's completion of chemotherapy treatment for cancer earlier in the year. The couple resides in Norfolk with their three children.
