Prince Haakon and Princess Mette-Marit also took the opportunity to pose for a more intimate photo with their kids. Haakon rests his arm on Prince Sverre Magnus’s shoulder, and both the father and son look dapper in suits and ties. Princess Ingrid Alexandra opted for a dark turtleneck and skirt with tights, while her mother sported a cozy white sweater and flowing black skirt.

The cheerful photo comes just months after Crown Princess Mette-Marit, 45, announced that shehas been diagnosed with chronic pulmonary fibrosis, which occurs when lung tissue becomes scarred and causes reduced oxygen supply in the blood. There is currently no way to reverse or slow down the damage to the lungs.
“For a number of years, I have had health challenges on a regular basis, and now we know more about what these are in,” Mette-Marit said in a statement. “The condition means that the working capacity will vary. The Crown Prince and I choose to inform about this now, partly because in future there will be a need to plan periods without official program. In connection with treatment and when the disease is more active, this will be necessary.”
