Today, King Constantine of Greece is celebrating his 80th birthday privately! Ten years ago, he celebrated his 70th birthday with a private party hosted by Crown Prince Pavlos and Crown Princess Marie Chantal in London with several royal guests including Queen Elizabeth and Princess Anne.

Queen Anne Marie wore a silk top with a pleated long skirt and a beaded jacket with Salvatore Ferragamo matching pumps.

Princess Tatiana wore a green embellished gown and matching bolero by Amanda Wakeley with a Valentino silver clutch and matching silver sandals.

Queen Margrethe wore a white and blue printed gown with a bow detail at the waist.

Princess Benedikte wore a green and blue striped short sleeve gown.

Queen Sofia wore a black column embellished gown with a matching bag and a blue shawl.
