In a recent court hearing, a former girlfriend of Høiby recounted an incident from a private birthday celebration for Queen Sonja, where she claims to have slapped him. This incident is part of a broader case against Høiby, who is facing charges for bodily harm, reckless behavior, vandalism, sexual misconduct, and breaches of a protection order issued against the woman. The incident reportedly took place at the royal couple's private summer residence, Mågerø, during Queen Sonja's birthday celebration in July 2024.

During her testimony, the woman described the atmosphere leading to the slap as extremely degrading, which caused her to become emotional. The incident reportedly occurred in the presence of guests celebrating the Queen's birthday, emphasizing the personal nature of the event and the seriousness of the allegations against Høiby. This revelation not only sheds light on the alleged misconduct but also raises questions about the challenges faced by those involved in high-profile relationships with members of the royal family.

This case, which involves a mix of personal relationships and legal implications, highlights the intersection of public figures' private lives with societal expectations and legal consequences. As the case unfolds, it brings attention to issues of domestic violence, respect for personal boundaries, and the complexities surrounding relationships with public personalities, particularly within the royal context of Norway.
