Prince Henrik of Denmark's condition has sadly taken a turn for the worse.
Queen Margrethe II's husband is currently Rigshospitalet in Copenhagen.
Last Friday, the Danish royal palace shared that his condition had "unfortunately greatly worsened".
In light of the tragic news, his nearest and dearest have stopped everything to be by his side.
Prince Fred, who cut short his Olympic visit, was joined by Princess Mary and their children Prince Christian, 12, Princess Isabella, ten, and seven-year-old twins Princess Josephine and Prince Vincent.
Fred's younger brother Prince Joachim and his sons Prince Nikolai, 18, and Prince Felix, 15 along with his wife Princess Marie were all spotted at the hospital.
Meanwhile, the Queen has been with her husband throughout.
Earlier this year, the 83-year-old's doctors had found a benign tumour in the prince's lung.
He was moved from the lung surgery department to the infectious department for further treatment.
In 2017, Henrik was admitted to hospital on several occasions before he was diagnosed with dementia.
"Following a longer course of investigation, and most recently, a series of examinations conducted during late summer, a team of specialists at Rigshospitalet has now concluded that His Royal Highness Prince Henrik suffers from dementia," the palace said in a statement at the time.
"The diagnosis implies a weakening of the Prince's cognitive function level. The extent of the cognitive failure is, according to Rigshospitalet, greater than expected for the age of the Prince, and can be accompanied by changes in behavior, reaction patterns, judgment and emotional life and thus also affect the interaction with the outside world."
"As a consequence of the diagnosis, the Prince will further downgrade his activities in the future, as well as the protection of protests and honors."
It concluded: "It is the Queen and the royal family's wish that the Prince in the future gets the peace that the situation demands."
