Crown Princess Mette-Marit's birthday fell on the day after major news for her family. On Aug. 18, Norway's state prosecutor charged her son Marius with 32 crimes, including one count of rape with sexual intercourse and three counts of rape without intercourse, CBS and Reuters reported.

Norway's Crown Prince Haakon said on Tuesday the royal family would continue to carry out official duties while his stepson stands trial next year accused of rape, adding that this is a challenging time for everyone involved.

Per People Magazine, Marius Borg Høiby, 28, was arrested in August last year on charges relating to the alleged physical and psychological abuse of a 20-year-old woman. He has since been charged with 32 crimes by the state prosecutor of Norway, including one count of rape with intercourse and three counts of rape without intercourse.
