Princess Maria-Olympia of Greece celebrated her 20th birthday in style, ringing in the milestone year with a glamorous celebration fit for a princess in Mykonos.
The Parsons student celebrated her birthday on 25 July. She marked her big day by posting a photo of herself with a friend writing: "It's ma birthdaaaaay!!!"
The royal opened up to HELLO! earlier this year about her birthday revealing that she would spend her day on the Greek island. At the time she said, "I'm really excited."
While she wasn't sure what her dad and mum, Crown Prince Pavlos and Crown Princess Marie-Chantal, had planned for her birthday, she told HELLO!: "Hopefully my parents will surprise me with something really fun!"
And it certainly looked fun! The 20-year-old's mum shared a video of the birthday girl dancing in Mykonos to Calvin Harris' hit summer song This Is What You Came For.
Attached to the clip, Marie-Chantal wrote: "Happy birthday my gorgeous 20 Year old @olympiagreece I love you sooooo much! blessed to have you in my life and I love you to infinity and beyond #Mykonos."
Olympia was joined by a group of pals dubbed the "Mykonos squad" for her celebrations. The squad look effortlessly stylish posing for photos on the picturesque streets of Mykonos, when they were not lounging on the beach or at the pool.
The birthday girl and her friends enjoyed breathtaking views of the Mediterranean Sea, while relaxing poolside in Mykonos.
Maria-Olympia looked chic wearing a little white dress and shades paired with a glowing tan, while out and about with friends on the Greek Island.
The royal's cousin Talita Von Furstenberg joined the fun, celebrating with the princess at the luxurious beach club Nammos in Mykonos.
