Mette-Marit, Crown Princess of Norway (born Mette-Marit Tjessem Høiby, pronounced [ˌmɛtːəˈmɑ̀ːrɪt ˈçɛ̀sːəm ˈhœ̀ʏbʏ], on 19 August 1973) is a member of the Norwegian royal family. She is married to Crown Prince Haakon, the heir apparent to the Norwegian throne.

A Norwegian commoner and single mother with a disadvantaged past, she was a controversial figure at the time of her engagement to Haakon in 2000. She became Crown Princess of Norway upon her marriage in 2001. The couple have two children, Ingrid Alexandra and Sverre Magnus, who are second and third in line to the Norwegian throne respectively. Mette-Marit additionally has a son from a previous brief encounter with Morten Borg, Marius Borg Høiby.

In October 2018, she was diagnosed with a form of pulmonary fibrosis. She is being treated at Oslo University Hospital and has restricted her royal duties.^[1]

Mette-Marit Tjessem Høiby was born in Kristiansand in the southern part of Norway, the daughter of Sven O. Høiby, who had been unemployed for some time but who had previously worked as a small-scale advertiser and journalist for a local paper in his hometown of Kristiansand, and Marit Tjessem, a former bank clerk. Her father was also a convicted felon, who had twice been convicted of violence.^[2] Her parents divorced, and her father later married professional stripper Renate Barsgård.^[3] She has a sister and two older brothers, including Per Høiby. Her step-brother, Trond Berntsen, by her mother's 1994 marriage to Rolf Berntsen, died in the 2011 Norway attacks.^[4] Mette-Marit grew up in Kristiansand, spending many weekends and holidays in the nearby valley of Setesdal and on the coast, where she learned to sail. During her youth, she was active in the local Slettheia youth club, where she was also an activity leader. As a teenager, she played volleyball, qualifying as a referee and coach.

After starting at Oddernes upper secondary school in Kristiansand, Mette-Marit spent six months at Wangaratta High School located in North East Victoria in Australia as an exchange student with the exchange organisation, Youth For Understanding. Later, she attended Kristiansand Cathedral School, where she passed her final examinations in 1994. She then spent several months working for the Norwegian-British Chamber of Commerce^[5] at Norway House in Cockspur Street, London. When her assignment in London ended, Mette-Marit relocated to Norway.

By her own admission, Mette-Marit had experienced a rebellious phase before she met Crown Prince Haakon Magnus.^[6] As a part-time student, she had taken six years, longer than usual, to complete her high school education before going on to take preparatory college courses at Agder College. She then worked on and off as a waitress at the restaurant Café Engebret in Oslo.^[7]

In the 1990s, Mette-Marit was in a relationship with John Ognby, a man convicted of drug-related offenses.^{[8][9][10][11]} Their relationship progressed to where they had bought her wedding dress for their planned wedding.^[12] A TV2 documentary titled Mette-Marit – vår tids Askepott focused on Mette-Marit's past.^[9] In 1997, she had a son with Morten Borg, who was also a convicted felon and one of Ognby's close friends.^[12]

In the late 1990s, Mette-Marit attended the Quart Festival, Norway's largest music festival, in her hometown of Kristiansand. She met Crown Prince Haakon at a garden party during the Quart Festival season.^[13] Years later, after becoming a single mother, she met the prince again at another party related to the festival.^[13]

Since marrying Haakon, Mette-Marit has taken several university-level courses. In 2012, she obtained a master's degree in executive management.^[14] Most of her ancestors were cotters and small farmers.^[15]

When the engagement between Crown Prince Haakon and Mette-Marit was announced, public and media reaction was negative, with many Norwegians being "horrified"^[16] and feeling that the Crown Prince's choice of partner was questionable; her lack of education, previous relationships with convicted felons and her socialization in a milieu "where drugs were readily available" were often cited by critics.^[17][18]

The couple married on 25 August 2001 at the Oslo Cathedral. Upon her marriage, she acquired the title, Her Royal Highness the Crown Princess of Norway.^[19] The couple have two children together: Princess Ingrid Alexandra, born 21 January 2004 at The National Hospital in Oslo and Prince Sverre Magnus, born 3 December 2005 at The National Hospital in Oslo.^[20]

At the time of their engagement, Mette-Marit was a single mother to a son named Marius Borg Høiby, born 13 January 1997 at Aker Hospital in Oslo,^[21] from her brief encounter with convicted felon^[22] Morten Borg. Høiby and Borg were never cohabitants or in a formal relationship. Mette-Marit has said of Marius: "Marius became a symbol of the unusual choice we made when we got married (...) he will not have a public role and is not a public figure."^[23] In 2017 he moved to the United States to attend an unspecified college.^[24] In 2018 media reported that he had falsely portrayed himself as "prince", although he has never held any title and is a commoner, not a royal.^[25] He was arrested in August 2024 after assaulting a woman at her apartment.^[26] Mette-Marit has been accused of warning her son about his impending arrest and of evidence tampering and witness tampering.^[27][28]

During 2002 and 2003, the Crown Princess attended lectures in development studies at the School of Oriental and African Studies at the University of London, apparently without graduating. She was also accepted as an intern at NORAD, the Norwegian government's development organization. The appointment received criticism due to her lack of relevant qualifications.^[29]

Crown Princess Mette-Marit is a patron of the Norwegian Red Cross and several other organizations.^[30][31] In 2010, Crown Princess Mette-Marit was named Young Global Leader under the World Economic Forum, and in 2012 she became a member of the international Foundation Board of the Global Shapers Community.^[30]

In 2015, Crown Princess Mette-Marit and Kate Roberts, senior vice-president of Population Services International, established Maverick Collective.^[30] On 26 April 2017, the Crown Princess was appointed as ambassador for Norwegian literature in the international arena.^[30]

Crown Prince Haakon and Crown Princess Mette-Marit established The Crown Prince and Crown Princess's Foundation. The purpose of the foundation is to identify and support projects for young people in Norway with the objective of strengthening youth leadership and integration.^[32]

In October 2018, she was diagnosed with pulmonary fibrosis, which will limit her official programmes.^[33] Mette-Marit, who has dealt with "health challenges on a regular basis" (such as pneumonia, several instances of norovirus, low blood pressure, along with some falls, concussions, a neck injury and a herniated disc),^[34] will undergo treatment at Oslo University Hospital.^[1]
