Princess Mary of Denmark and Sweden’s Princess Victoria dazzle in diamond tiaras and stunning gowns as they lead the glamorous guests at Danish Prince Christian’s 18th birthday gala

To celebrate Prince Christian’s 18th birthday, the royals of Europe gathered in Copenhagen for a gala dinner last night.

Guests including Princess Mary of Denmark, Princess Victoria of Sweden and Princess Mette-Marit of Norway all looked straight out of a fairytale as they attended the glamorous party at Christiansborg Palace.

The birthday boy’s mother, Mary, 51, who is married to Prince Frederik, the heir apparent to the Danish throne, put on a dazzling display in the diamond tiara she wore on her wedding day in 2004.

Looking effortlessly elegant, the Australian-born mother-of-four opted for a gem-encrusted blue gown from Danish designer Jesper Høvring and a pair of shimmering diamond drop earrings.

Sweden’s Victoria, 46, who is heir to her country’s throne, appeared just as radiant in a cream Elie Saab gown with a square neckline that showed off her statement diamond necklace.

Adding a pair of diamond earrings and an eye-catching tiara to finish off her look, the princess attended the occasion alongside her husband Prince Daniel, 50, and her 11-year-old daughter, Princess Estelle.

Victoria and Estelle weren’t the only glamorous mother and daughter duo at the gala, with Crown Princess Mette-Marit of Norway, 50, and her daughter Princess Ingrid Alexandra, 19, wearing matching blue gowns and sparkling tiaras.

They were joined by Princess Catharina-Amalia of the Netherlands, 19, and Princess Elisabeth of Belgium, 21.

Catharina-Amalia looked stylish in a caped dress from Essentiel Antwerp, with her long hair down and pinned back with a diamond tiara. 

Elisabeth, meanwhile, looked every inch the princess in a cream sleeveless gown from Belgian couture brand Natan, which she teamed with matching gloves.

Other picture-perfect guests included Crown Prince Haakon of Norway, Crown Prince Frederik of Denmark and Princess Benedikte of Denmark.

The party saw hundreds of well-heeled guests from across Europe present, such as Queen Anne-Sophie of Greece, Crown Prince Pavlof of Greece and Crown Princess Marie-Chantal of Greece.

Meanwhile, perhaps showing that Denmark’s royal title row is truly behind them, Prince Joachim attended his nephew’s party – after last year criticising his mother Queen Margrethe’s decision to strip his children of their prince and princess titles. 

He was joined at the gala by his wife Princess Marie, and their children Count Henrik of Monzepat and Countess Athena of Monpezat. Count Felix of Monpezat, Joachim’s second eldest son from his first marriage, was also at the event.

As well as the gala, on the eve of Christian’s birthday, a documentary giving an insight into the teenager’s life was broadcast to mark his milestone.

According to the palace, the production gives Danes the chance to get ‘up close and personal’ with the prince like never before.

It shows the royal learning about institutions in Danish society and gives an insight into his relationship with his father.

Christian, who is a four-times great grandson of Queen Victoria and fifth cousins with Princes William and Harry, was followed by cameras last August, as he took ‘King lessons’ alongside his father.  

‘Together, they undertake this adventure with a clear mission: to ensure that Prince Christian knows better the country of which he will one day be king,’ the Palace said in a statement.

The documentary reportedly shows him meeting with Danish Parliament, as well as members of the Supreme Court and representatives from the Danish church.
