Norwegian royals don traditional dress as they unveil new family portrait ahead of Prince Sverre Magnus’s 18th birthday

A new photo of the Norwegian royal family has been released ahead of Prince Sverre Magnus’ 18th birthday.

The youngest child of Crown Prince Haakon and Crown Princess Mette-Marit will celebrate his coming of age on December 3, when he officially turns 18.

The Norwegian royals got their celebration a little early by posing together in a stunning new portrait session held in Oslo, Norway.

Celebrating with the prince was his father and heir to the Norwegian throne, Prince Haakon, along with his wife Princess Mette-Marit, both 50 years old. Both stood next to the prince’s only sister, Princess Ingrid Alexandra, 19.

The brilliant images also feature his grandfather and the king of Norway, King Harald, 86, as well as his wife and the prince’s grandmother Queen Sonja, also 86.

Meanwhile, Mette-Marit’s mother Marit Tjesem, who recently mourned the loss of her long-time partner Magnar Alfred Fjeldver, also appeared in the commemorative photographs.

The beaming prince, third in line to the Norwegian throne, appeared in the most cheerful mood as he donned a traditional dress, which he paired with a pair of black loafers adorned with a sparkling buckle.

Most of the family wore tailored suits, with the exception of King Harald, who wore a smart dark blue suit, multi-colored striped tie, and black leather shoes.

The camera captured the family at their happiest, with the prince even posing on his knees for a few photos.

However, their daughter Ingrid Alexandra did not appear at the celebration.

The Crown Princess wore an elegant Norwegian traditional dress in dark blue, a white blouse and black leather boots.

Prince Haakon chose to wear the men’s bunad suit – traditional Norwegian costumes that include knee socks and white shirts, as well as red spots – which features prominently on the country’s flag.

Sverre chose a smart navy blue suit with a purple tie and smart black leather shoes.

They were also accompanied by their beloved dog Molly, whose neck was adorned with neckerchiefs in the red and blue colors of Norway.

The holiday, celebrated annually on May 17, commemorates the signing of the constitution that established Norway as an independent kingdom in 1814.

The constitution declared Norway an independent kingdom in an attempt to avoid being handed over to Sweden after the devastating defeat of Denmark and Norway in the Napoleonic Wars.

Celebrations that take place across the country include parades as well as royal appearances where the family is greeted by a crowd of public.

The Norwegian monarchy is one of the oldest in the world. The position of King of Norway has existed continuously since the unification of the country in 872.

And in 1905, after the dissolution of the union with Sweden, Haakon VII, the grandfather of the current king, was elected to the throne by popular vote.
