Prince William celebrated his 42nd birthday with a joyful family photo taken by his wife, Kate Middleton, showcasing him and their three children jumping on a beach in Norfolk. Kate, who is undergoing cancer treatment, also made her first public appearance in six months at the Trooping the Colour parade. King Charles shared a throwback photo and sweet birthday message for Prince William. Despite recent challenges, including both Kate and King Charles battling cancer, William continues performing his royal duties. The family recently shared another beach photo for Father's Day, highlighting their tradition of releasing personal images on significant occasions. Speculation remains about the future roles of William's children, as he supports a slimmer monarchy approach.
