Happy Birthday to Crown Prince Haakon of Norway, who turns 44 today. The only son of King Harald V and Queen Sonja, he is the younger brother of Princess Martha Louise, and was born during the reign of his grandfather, King Olav V. Educated in Norway, the United States, and the United Kingdom, in 2001, he married Mette-Marit Tjessem Høiby, a single mother. The couple have three children, Princess Ingrid Alexandra and Prince Sverre Magnus, as well as Marius Borg Høiby. Crown Prince Haakon undertakes official duties, within Norway and around the world. I wish HRH a very Happy Birthday and Many Happy Returns!
