OSLO – Norway’s Crown Princess Mette-Marit has undergone a successful lung transplant and is recovering from the procedure, the royal household said ​in a statement on Wednesday.

The 52-year-old wife of Crown Prince Haakon, the heir to ‌the Norwegian throne, was diagnosed with pulmonary fibrosis in 2018, a chronic disease that causes scarring in the lungs and leads to a reduced oxygen uptake.

“Like all newly transplanted patients, the crown princess will remain at the hospital for ​several weeks to come,” Oslo University Hospital Professor Are Holm said in a statement provided ​by the palace.

The surgery comes at a strained time for the royal family: earlier ⁠this week, Mette-Marit’s 29-year-old son from a previous relationship, Marius Borg Hoiby, was convicted of rape ​and domestic violence and sentenced to four years in prison.

Oslo University Hospital on June 5 said Mette-Marit had been ​placed on a waiting list for a lung transplant after a significant deterioration in her health that likely gave her only a year to live without the surgery.

The crown prince and crown princess thanked the public for the warm and ​kind greetings they had received recently, the palace said. The next public update on her health ​is only expected when she is discharged from hospital, it added.

Crown Prince Haakon in December said the family had noticed ‌a ⁠change in Mette-Marit’s condition and that she was struggling more to breathe.

Prime Minister Jonas Gahr Stoere had praised the crown princess for being open about her illness, saying this could help others suffering from similar conditions.

Mette-Marit was 25, an unmarried single mother and a commoner when she met Haakon at a music ​festival in 1999 — the ​beginning of an unlikely ⁠royal romance that started with a media furore and ended up winning over much of the nation.

ROYAL FAMILY HIT BY SCANDALS

But support for Norway’s monarchy ​has taken a hit this year, opinion polls have shown, as several scandals ​hit at ⁠once.

Hoiby’s conviction on Monday followed a highly publicized trial that dominated headlines.

Meanwhile, the crown princess has apologized to the king and queen for her contact with late U.S. sex offender Jeffrey Epstein, whom she had described as ⁠a friend, ​though she cut ties several years before his death in ​2019.

A Norstat survey in February, conducted during Hoiby’s trial, showed support for retaining the monarchy falling to a record low of ​60%, before recovering slightly to 64% in May.
