Princess Olympia celebrated her 21st birthday in style on Tuesday in Mykonos. The Greek royal marked the occasion with a cheeky Instagram photo in her “birthday suit” – a retro Lisa Marie Fernandez red bikini – next to silver “21” balloons.
The Princess' family also took to social media to shower the birthday girl with love. Crown Princess Marie-Chantal shared a candid snapshot of her only daughter from her husband Crown Prince Pavlos and Olympia's joint birthday celebration earlier this month.
"Happy birthday Olympia sweet child of mine! You are beautiful inside and out and let that sunshine energy always shine on love you love you ooh I just love you," the mum-of-five wrote alongside the photo.
Crown Prince Pavlos also posted a shot from his and Olympia's lavish birthday celebration writing, "Happy Birthday my darling beautiful @olympiagreece The world is your oyster and I am the proudest father ever ❤️❤️Χρόνια Πολλά ❤️.."
Meanwhile younger brother Achileas-Andreas, 16, opted for a throwback of himself with the Olympia and their brother Constantine, 18 as kids, which he simply captioned: "Happy 21st birthday Olympia! I love you ."
Olympia opened up to HELLO! last year about her family relocating to New York, where she studies, admitting, "I'm really excited. I'm just so close to my family and my brothers – Princes Constantine, Achileas-Andreas, Odysseas-Kimon and Aristidis-Stavros – so I’m really excited to have them back."
