Royal wedding alert: Princess Beatrice, Alessandra de Osma and more go glam at fairy tale affair

Prince Jean-Christophe Napoleon Bonaparte and Countess Olympia von und zu Arco-Zinnerberg's wedding was held at the historic Cathédrale Saint-Louis-des-Invalides on the Invalides Memorial Complex in Paris, France. The bride recieved a traditional escort into her wedding with her father Count Riprand von Arco-Zinneberg taking her arm. From the moment she stepped onto the scene, her lacey and leafy gown and flowing veil demanded attention.

The bride melded custom wedding dress with couture uniquess in an Oscar de la Renta gown from the Fall 2019 collection. Crafted from a lovely lace pattern, the ornate and eyecatching design was a stunning choice for the Countess.

Jean-Christophe Napoleon kept things traditional in his royal suit. He was all smiles outside the church with mom Princess Beatrice de Bourbon Siciles.

Olympia had the most adorable party of five bridesmaids. The little ones wore matching white dresses with aqua satin sashes (sound familiar?) and elegant flower crowns.

Fellow newlyweds Prince Christian de Hanover and his wife Princess Alessandra de Osma attended the ceremony. Alessandra looked lovely in a floral frock.

Princess Olympia of Greece joined her father Prince Paul at the wedding. The 23-year-old royal struck a stylish pop of color to her ensemble with the most incredible pair of pink lightning bolt heels by Prada.

Soon-to-be wed Princess Beatrice and Edoardo Mapelli Mozzi looked very much in love as they attended the affair. The British royal was stunning in a floral silk-satin tea dress with a Peter Pan collar by The Vampire's Wife. She paired The LA Dress with a pale blue Topshop trench coat, black Carvela Lulu heels and a peach satin boater hat by Julian Garner.

Jean-Christophe and Countess Olympia's union was a historic one. The 33-year-old equity manager is the great-great-great nephew of Napoleon Bonaparte, while the 31-year-old is the great-great-great niece of Napoleon's wife Archduchess Marie-Louise of Austria. Their marriage has united the former Imperial House of France and the House of Hapsburg once again!

What's a royal wedding without a top of the stairs smooch? The newlyweds proclaimed their love for each other as they left the Saint-Louis-des-Invalides Cathedral at the Invalides Memorial Complex.

The lovebirds hopped a sweet ride home from the wedding: a red vintage DS Citroen. Though a few rain showers fell, skies quickly cleared and they were able to roll the top down as they drove off into the exciting next chapter of their lives.
