King Willem-Alexander and Queen Maxima shared a beautiful photograph with their daughters to mark the Dutch monarch's 56th birthday on Thursday – but one family member was missing from the snap.
The palace posted the image of the King and Queen, alongside Princess Catharina-Amalia, 19, Princess Ariane, 16, and the family's pet dog, Mambo, before they headed to Rotterdam for the King's Day celebrations.
But Willem-Alexander and Maxima's middle daughter, Princess Alexia, was missing from the photoshoot.
The 17-year-old is currently at UWC Atlantic College in Wales where she will complete her two-year International Baccalaureate this spring.
UWC is set in the 12th century St Donat's Castle on the southern Welsh coast and campus facilities include a library, woodland, an indoor and outdoor swimming pool, and classrooms within historic buildings.
