It’s not every day that you turn 50 on your son’s birthday. And yet, Crown Princess Marie-Chantal of Greece did just that on Monday, September 17, pulling out all the stops for her milestone occasion. The Crown Princess made it a joint affair as she shares a birthday with her son, Prince Odysseas Kimon, who turned 14. While the pair made for sweet party honorees, it was their festive confections that stole our attention. After all, double the celebration means double the cakes!

While Princess Marie-Chantal appears to have had a low-key family birthday celebration, her husband Crown Prince Pavlos and daughter Princess Olympia hosted a lavish joint party in honor of their own 50th and 21st birthdays back in 2017. The father-daughter duo were treated to a royal-studded party held at a manor in Gloucestershire. The masquerade soirée, whose theme was "Prince and the Revolution," was attended by a number of European royals including Queen Maxima of the Netherlands and Norway's Crown Prince Haakon and Crown Princess Mette-Marit and Rosario Nadal — the wife of Prince Kyril of Preslav. Other A-List guests included Nicky and Paris Hilton, designer Valentino, Poppy Delevingne and Tory Burch.

During the glamorous party, Pavlos delivered a heartwarming speech about his daughter saying, "In your life you have done a lot of things that has impressed, depressed, driven us crazy. Let me tell you few things about life with Olympia. First of all you’re beautiful. You’re full of energy. Energy that comes from your mother."
