King Willem-Alexander and Queen Maxima of The Netherlands shared some beautiful new photographs of their middle daughter, Princess Alexia, to celebrate her milestone 18th birthday on Monday.
The portraits were taken at the Dutch royal family's home, Huis ten Bosch, in the Hague, and show close-ups of the princess smiling at the camera.
Alexia can be seen wearing a white belted shirt dress and tan heels, with her auburn locks styled in a bouncy blow-dry. In a third snap, the princess is pictured wearing a navy-blue ensemble, which she accessorised with layered gold necklaces.
It's not known how Alexia will celebrate her special day, but it's likely that she will spend her birthday privately with family and friends.
The Dutch royal palace also announced on Monday that the king has appointed Princess Alexia, Knight Grand Cross of the Order of the Netherlands Lion and Knight of the House Order of the Golden Lion. She also now has her own personal standard, which features the national coat of arms in the middle of the flag.

She attended Christelijk Gymnasium Sorghvliet for the first four years of her education, before studying for her International Baccalaureate at the United World College of the Atlantic (UWC Atlantic College) in Llantwit Major in Wales.
