Princess Catharina-Amalia will mark her 21st birthday on 7 December, and there are reports that the Dutch heir will throw an extravagant ball to celebrate the milestone occasion.
When the Princess turned 18 in 2021, the world was in the middle of a global pandemic and she was unable to host a gala dinner like some of her European counterparts, including Norway's Princess Ingrid Alexandra and Denmark's Crown Prince Christian.
According to Point de Vue, preparations for a grand ball for Catharina-Amalia's 21st birthday are reportedly underway, although the Dutch palace is yet to confirm any plans.
If a gala dinner goes ahead, guests are likely to include other European heirs, with a white-tie dress code.
The next generation of royals gathered in Oslo for Princess Ingrid Alexandra's belated 18th birthday banquet in June 2022 and in Copenhagen for Crown Prince Christian's milestone in October 2023.

King Willem-Alexander revealed earlier this year that his daughter lived in Madrid in 2023 under the protection of the Spanish monarchy.
The Dutch king and queen are also parents to Princess Alexia, 19, who is a student at University College London, and Princess Ariane, 17, who is in the middle of her international baccalaureate at UWC Adriatic in Italy.
