In 2018, the Crown Princess was diagnosed with pulmonary fibrosis, a condition that affects the lungs over time.
After the Royal House announced her diagnosis, it was revealed that Mette-Marit’s official engagements would be dependent on her health and medical treatment.
Health fears for the princess were fuelled last week after she was absent from a visit King Harald, Queen Sonja and Crown Prince Haakon made to Gjerdrum following a catastrophic landslide.
However, it is now thought the Crown Princess was not present due to the fracture of her tailbone.
