The party is said to have got "completely out of hand" and continued in the basement, whilst Marius's stepfather Crown Prince Haakon and his two siblings slept upstairs.
THE son of Norway's Crown Princess allegedly raped a TV presenter at a castle basement party - and police are believed to have a video of the claimed attack.
The fresh allegations against Marius Borg Høiby, 28, son to princess Mette-Marit, are the latest in a scandalous saga involving the royal.
The presenter had been at a glam "party among friends" in the basement of royal pad Skaugum Castle in 2018 with Marius - who was just 21 at the time.
Allegations against Marius came to light when cops reportedly found three videos and more than 10 photos of an incident in the basement on his laptop.
