Princess Ingrid Alexandra of Norway is celebrating her 18th birthday — and royals from around Europe are joining in for the fun.

Although the daughter of Crown Prince Haakon and Crown Princess Mette-Marit, who is second in line to Norway's throne, turned 18 in January, celebrations were put on hold amid the COVID-19 pandemic. But on Friday, royals from different countries came together for a gala — complete with glamorous ballgowns and tiaras!

Ahead of the party, four future queens of Europe and a future grand duke gathered for a portrait. Princess Ingrid Alexandra took the center spot in a purple dress and the Boucheron Circlet Pearl Tiara, which originally belonged to her great-great-grandmother Princess Ingeborg of Sweden.

Standing in the back row are Princess Catharina-Amalia of the Netherlands, 18, and Princess Elisabeth of Belgium, 20 — both daughters and heirs of current kings.

Princess Ingrid Alexandra was seated between Princess Estelle of Sweden, 10, and Prince Charles of Luxembourg, 2.

While Princess Estelle sported a floral headband that perfectly matched her blue dress for the photo op, the other princesses sported tiaras — for the first time ever!

Princess Catharina Amalia wore the Dutch Star Tiara while Princess Elisabeth wore a sparkler that hasn't been seen before. Princess Ingrid Alexandra also wore the Boucheron Circlet Pearl Tiara in a series of portraits released on Friday to celebrate the occasion.
