On top of multiple yacht parties, photos shared online also seemed to show Olympia attending a family dinner organised by her parents, several clips of her dancing, and two separate birthday cakes.‌Olympia shared a series of snaps from her weekend adventures on Instagram, which seemed to show her kicking off her birthday festivities with a lavish get-together on a yacht. Another photo, shared by her father, showed the model posing in a grey bikini alongside both her parents.‌Another photo shared by Pavlos showed the blonde beauty cutting into a chocolate cake while sitting at a table on the yacht, where crystal blue water could be seen in the background alongside striking white cliffs.The Crown Prince captioned his photos: "Happy Birthday, dear Olympia, you are my sunshine."‌In a video shared by Olympia's mother, it was then confirmed that the princess's brothers, Achileas and Constantine Alexios, also joined in the celebrations, as they were seen carefully carrying a giant cake decorated with raspberries.Olympia was filmed blowing out the candles on her cake while her guests, including Norwegian singer Peter Dundas, photographer Alexia Mavrolleon, and one of Olympia's long-term friends, Evangeline, all sang happy birthday to her.‌Photos and videos shared on Olympia's own Instagram account then showed other lavish parties she attended over the weekend. In several clips, she can be seen dancing under flashing lights, posing with her friends, and having what appeared to be a karaoke session.In one very short clip of Olympia posing at a party, her Argentinian businessman boyfriend, Martin Pacanowski, could be seen standing beside her. The couple were first linked together in 2024, but she has kept their romance private and never posted him on social media before her birthday event.While Princess Olympia and the rest of her family continue to use their royal titles, Greece technically no longer has a royal family. Olympia's grandparents, Constantine II of Greece and Anne-Marie of Denmark, were the last King and Queen of the Hellenes, after the 1974 Greek public referendum voted to abolish the monarchy.Article continues belowContent cannot be displayed without consentOlympia's father is now the head of the family following the passing of Constantine II in 2023. While the model was born in New York, she and her family relocated to London when she was young, and she spent most of her childhood in the UK.The family are very close to the British monarchy, as proven by King Charles, who at the time was Prince Charles, agreeing to be Olympia's godfather when she was born in 1996.
