The Crown Prince's Children: Duty, Military Service, and a Future Queen

The three children of Crown Prince Haakon and Crown Princess Mette-Marit—Princess Ingrid Alexandra, Prince Sverre Magnus, and Marius Borg Høiby—have seen the most significant and dramatic developments in their lives throughout 2024 and 2025. Their paths highlight the stark differences between a life of royal duty and the challenges faced by an individual seeking a private life under the royal spotlight.

Princess Ingrid Alexandra: From High School to the Military and Abroad

Princess Ingrid Alexandra, the second in line to the throne, has spent 2024 and 2025 undertaking a pivotal transition year that is preparing her for her eventual role as Norway’s head of state. Following her graduation from high school in 2023, the Princess began her mandatory military service in the fall of 2024 with the Engineer Battalion in Brigade North. Her service is set to continue into 2025, where she has been serving as a combat engineer soldier and a gunner on a CV90 armoured vehicle.

Looking ahead, the future Queen of Norway is set to make a significant move abroad. The royal court has confirmed that Princess Ingrid Alexandra will begin her university studies at the University of Sydney in Australia starting in August 2025. This international move is a major step in her education, providing a period of study outside of Norway before she commits to full-time royal duties.

Prince Sverre Magnus: A New Chapter in Italy

Prince Sverre Magnus, who celebrated his 20th birthday in December 2025, is currently third in the line of succession. In a move that mirrors his sister's international focus, the Norwegian palace confirmed in late 2025 that Prince Sverre Magnus had made an unexpected move abroad, relocating to Italy. While details about his specific activities are private, this period abroad is seen as a personal pursuit of education and experience before he takes on more public responsibilities.

The Marius Borg Høiby Legal Case: A National Scandal

The most shocking development to impact the royal family in 2025 involved Marius Borg Høiby, Crown Princess Mette-Marit's eldest son from a previous relationship. Despite not holding a royal title and seeking a private life, Marius remains a prominent public figure. In August 2025, he was indicted by Norwegian prosecutors on 32 different offenses, including multiple serious charges. The charges are highly sensitive, and he faces a potential prison sentence of up to 10 years if convicted.

The case has dominated Norwegian and international media, with his trial expected to commence in early 2026. The Crown Princess and the entire family have maintained a private stance on the matter, though the situation has undoubtedly placed immense stress on the royal household.

Princess Märtha Louise's Daughters: The Influencers and Creatives

The three daughters of Princess Märtha Louise and the late Ari Behn—Maud Angelica, Leah Isadora, and Emma Tallulah—have forged paths that are distinctly modern and non-traditional for royal descendants. They are celebrated for their individuality, creativity, and willingness to use social media to build their personal brands, often referred to as Norway's "influencer royals."

Maud Angelica Behn: Author and Emerging Artist

Maud Angelica Behn, the eldest of the Behn sisters and Queen Sonja's first grandchild, has established herself as a talented artist, illustrator, and author. In 2024, she continued to build her reputation in the art world, holding an exhibition opening at Soli Brug in Greaker in April. Maud has also become a prominent advocate for mental health awareness, a cause she has championed since the passing of her father, Ari Behn, in 2019. Her public speaking and work in the arts have positioned her as a thoughtful and influential young voice in Norway.

Leah Isadora Behn: Beauty Influencer and Entrepreneur

Leah Isadora Behn has successfully leveraged her public profile to become a major figure in the beauty and social media industry. In a significant entrepreneurial move in 2024, Leah launched her own makeup brand named "dorah," a venture that cemented her status as a "royal influencer." She regularly attends high-profile events, including the Vixen Awards 2024, where she makes fashion statements that showcase her unique style. Leah is currently sixth in the line of succession and has amassed a significant following across platforms like Instagram and TikTok.

Emma Tallulah Behn: The Equestrian Talent

The youngest of the Behn sisters, Emma Tallulah, is a talented equestrian athlete. Born in 2008, she is currently focused on her competitive career, participating in events like the Youth Continental/Regional Championships in 2024. Like her sisters, Emma was a central figure at her mother's highly publicized wedding to Durek Verrett in 2024, bringing together the entire extended family for a major public event. Her dedication to show jumping demonstrates a focus on personal passion outside of the royal sphere.

The Future of Queen Sonja's Grandchildren and the Monarchy

The collective activities of Queen Sonja's six grandchildren illustrate the dynamic and evolving nature of the Norwegian Royal Family. The family is clearly embracing a dual existence: one committed to traditional royal duties, exemplified by Princess Ingrid Alexandra's rigorous preparation for the throne, and another that is modern, independent, and entrepreneurial, as seen in the Behn sisters' careers.

The next few years will be defined by these pivotal life events. Princess Ingrid Alexandra's time in Australia will be a closely watched period of personal growth, while Prince Sverre Magnus’s move abroad signals a desire for a degree of anonymity and personal development. The ongoing legal proceedings involving Marius Borg Høiby will continue to test the family's resilience and public image. Ultimately, these six individuals are not just descendants of royalty; they are a reflection of a modern monarchy that must balance centuries of tradition with the realities of 21st-century life, ambition, and scrutiny.
