On July 2, 2017, Crown Princess Marie-Chantal celebrated her husband and daughter's birthday in a star-studded joint birthday Bash. However, it is safe to say that the party was more for daughter Maria Olympia's 21st birthday which would happen on July 25th. Among the many guests were: Queen Maxima of the Netherlands,  Crown Princess Mette-Marit and husband Crown Prince Haakon, Prince and Princess Michael of Kent, Paris and Nicky Hilton, and Valentino Garavani.

For the party, Crown Princess Marie Chantal wore a custom Gucci gown that was embroidered with the words "Revolution" and "Prince". The dress also was embellished with what looks to be a sequin strawberry or pepper. She teamed the unique dress with an even more unique Philip Treacy star head piece.

Maria-Olympia's outfit has already been covered by the lovely Brittani, but just in case you all forgot, "Olympia" wore a Steven Khalil embellished one-piece outfit with a train, platform Gucci sneakers, and a Philip Treacy head piece. 

This birthday bash was one of the most extravagant royal birthday parties that took social media websites by storm, showing a different side of the royals we all know and love. Guests were even encouraged to use the hashtags #5021revolution and #princeandrevolution to show the multiple experiences happening at the party.
