When he entered public life fifteen years ago he was often referred to as "little Marius", but time flies and today the Crown Prince's stepson, Marius Borg Høiby, turns eighteen and thus reaches his majority.
Marius Borg Høiby was born to the then Mette-Marit Tjessem Høiby and Morten Borg on 13 January 1997 and was still just two years old when his mother began a relationship with the Crown Prince in 1999. His family understandably tried to shield him from unwelcome media attention, but many will remember him playing with the Queen on the floor of the Royal Lodge during the 2000 Christmas photo session and as a pageboy at his mother's and stepfather's wedding on 25 August 2001.
The King decided that Marius should be a member of the royal family, but not of the royal house, which means that he is a natural presence at family events, but does not take part in official events that are not family events, except for the occasional more informal event, such as a football match or a concert. Thus he does for instance not join his siblings on the palace balcony on the National Day and it is not expected that he will carry out official engagements or represent Norway abroad as an adult.
So far, the media have mostly left Marius alone, but it remains to be seen whether his unusual position will provide him with the best of both worlds or if his royal status will restrict him in trying to lead a normal life.
