People.com Royals See a Sneak Peek of Prince Charles' Palace Birthday Party in Glam Pic with Wife Camilla Prince Charles and his wife Camilla posed for a photo before heading to his birthday party at Buckingham Palace By Robyn Merrett Published on November 14, 2018 06:31 PM Share Tweet Pin Email Prince Charles is celebrating his 70th birthday in style! On Wednesday, Charles was photographed with his wife Camilla, Duchess of Cornwall moments before heading to his birthday party hosted by his mother Queen Elizabeth at Buckingham Palace. For the special evening, Charles sported a black tuxedo while Camilla chose a stunning off-the-shoulder navy gown and accessorized her look with dangling diamond earrings and a diamond necklace. Inside the party, Queen Elizabeth made a sweet speech praising her eldest child and heir to the throne, noting that she was honored to be there to experience the milestone. “It is a privilege for any mother to be able to propose a toast to her son on his 70th birthday,” the 92-year-old monarch began. “It means that you have lived long enough to see your child grow up. It is rather like — to use an analogy I am certain will find favor — planting a tree and being able to watch it grow.” Prince Charles Gives Squirrels Names and Lets Them in the House, Prince William Reveals Prince Charles, Prince of Wales and Camilla, Duchess of Cornwall.

And she was heard to observe that 70 is exactly the age when the number of candles on your cake finally exceeds the amount of breath you have to blow them out.” In addition, she went on to praise Charles’ dedication to saving the environment and raising a family. “Over his 70 years, Philip and I have seen Charles become a champion of conservation and the arts, a great charitable leader — a dedicated and respected heir to the throne to stand comparison with any in history — and a wonderful father,” the monarch said. “Most of all, sustained by his wife Camilla, he is his own man, passionate and creative.” Happy 70th Birthday, Prince Charles!
