Future queen Princess Catharina-Amalia looks so regal in new birthday portrait

The Dutch royal palace shared a beautiful new portrait of Queen Maxima and King Willem-Alexander's eldest daughter to mark her 20^th birthday on Thursday.

Pictured at the Huis ten Bosch palace, Princess Catharina-Amalia looked elegant in a black blazer co-ord by Italian brand Marina Rinaldi.

The future queen accessorised with delicate gold jewellery, including dainty rings and a disc necklace.

Her blonde locks were styled in loose waves and she opted for smokey eye makeup, matte lipstick and a sweep of bronzer.

The Princess is currently in the second year of her degree at the University of Amsterdam, where she is studying a combined course of Politics, Psychology, Law and Economics, but she was forced to move out of her student accommodation last year, due to security threats.

In October, Catharina-Amalia was among the European heirs to attend Prince Christian's 18th birthday gala dinner in Copenhagen, Denmark.

Princess Catharina-Amalia Beatrix Carmen Victoria was born on 7 December 2003 at HMC Bronovo in The Hague as the eldest child of Queen Maxima and King Willem-Alexander.

She also has two younger sisters, Princess Alexia and Princess Ariane, born in 2005 and 2007 respectively.

She was also among the foreign royals to attend a reception at Buckingham Palace on the eve of King Charles and Queen Camilla's coronation in May.
