King Charles and Queen Camilla have shared a sweet birthday tribute to Prince William this morning, as the Prince of Wales turns 43.
The royal couple posted a photo on their official Instagram page and shared their well wishes. The image of the Prince of Wales, shared earlier this year on his visit to farmland owned by the Duchy of Cornwall in Bath, shows him smiling widely while sat on a rock wall. The caption on the picture read: "Happy Birthday to The Prince of Wales!" followed by a balloon and confetti emoji to mark the celebration.
And while the Royal is celebrating his 43rd birthday today (Saturday, June 21), Royal fans say Prince William is 'ageing like a fine wine'. Fans also spotted an adorable detail about his marriage to Kate Middleton. At an event earlier this week, people were delighted to see the future king grinning at his wife.

The couple appeared united as they attended the Order of the Garter in Windsor on Monday (June 16), where William sported the dark blue velvet mantles, the insignia of the order, and the distinctive feathered bonnet. Meanwhile, Kate stunned in an all-white ensemble, including a Self-Portrait dress and matching wide-brim hat.
"A brilliant celebration of tradition, service and duty. Thank you to everyone involved." Fans were quick to comment on the post, with one person writing: "Those two are aging like a fine wine!"
Meanwhile, others spotted the look of 'true love' Princess Kate appeared to be giving her husband. One wrote: "20+ years & 3 adorable children[...] Catherine only has eyes for Prince William. This is true love."
Meanwhile someone else added: "What a treat for us Royal watchers! Princess Catherine looks absolutely stunning and Prince William as handsome as ever!" Another fan added: "Prince William and Princess Catherine look absolutely stunning and majestic!!"
Fans may now be speculating as to whether William's estranged brother, Prince Harry, will wish him a happy birthday this year.
The brothers are not thought to be on speaking terms, however the Duke of Sussex received a surprise birthday message from the various members of the Firm on social media on his birthday in September last year.

Taking to X, the Royal Family shared a snap of a smiling Harry to mark his 40th birthday. The message, complete with a cake emoji, said: “Wishing The Duke of Sussex a very happy 40th birthday today!”
Meanwhile, William and Kate’s X account shared an almost identical message. It read: “Wishing a Happy 40th Birthday to The Duke of Sussex!” At the time of writing, it remains to be seen whether Harry will return the favour for his brother's birthday.
Meanwhile, the Princess of Wales and the couple's three children paid tribute to William earlier this month to mark Father's Day. On the Prince and Princess of Wales' official X page, a post read: "Happy Father’s Day, Papa (before and after!) We love you! G, C & L," referring to Prince George, Princess Charlotte and Prince Louis, aged 11, 10 and seven respectively.
