Crown Princess Mette-Marit at King Willem Alexander's 40th Birthday

On 1st September 2007 Crown Princess Mette-Marit and Crown Prince Haakon made an appearance at the birthday celebrations of their Dutch counterpart King Willem Alexander. At the time Willem Alexander was simply the heir - known as the Prince of Orange - and was yet to take the throne. 

The Dutch soon to be King's birthday is actually in April but celebrations were delayed after the birth of his daughter. He celebrated his birthday by hosting a reception at Het Loo Palace for friends, family, and members of foreign royal families. 

The Crown Princess arrived at the event on her husband's arm. She was wearing a blush pink gown with silver embroidery and a black bow under the bust. One of our wonderful Co-Editors discovered that the dress is by Norwegian designer Karina Kjenner Titze. 

Mette-Marit was just one of many royals who attended the event. Other guests included Spain's Queen Letizia and King Felipe and Belgium's Queen Mathilde and King Philippe. When the future Queen of Norway arrived, she was accompanied by Crown Princess Victoria of Sweden in a brown dress.
