In April, Queen Elizabeth II turned 91 years old.
With 65 years on the throne, she's one of the longest-reigning monarchs in recorded history, and she remains beloved across the globe thanks to her tireless humanitarian efforts and refreshingly no-nonsense attitude.
Sadly, if a new report is to be believed, the Queen's health is failing, and her loved ones have been cautioned that she may be nearing the end.
Several media outlets are reporting today that the Queen's private secretary, Sir Christopher Geidt, has advised her family to pack black clothing for any upcoming travel, as they may need to dress in appropriate mourning attire in the weeks to come.
There's been no official word from Buckingham Palace, but it's believed that the Queen is in failing health and being treated at home.
Thus far, there's been no change in the Queen's appearance schedule, but she's been booking far fewer official engagements in recent years due to her advanced age.
Earlier this year, the Queen's husband, Prince Philip, retired from public life at the age of 96.
Obviously, the Queen will be mourned throughout the world when she passes, but in some circles, talk has already turned to the matter of succession.
As Elizabeth's eldest son, Prince Charles is next in line for the throne.
At the age of 68, he's the oldest heir apparent for the British crown in over 200 years.
Since no royal engagements have been canceled, it seems the Queen isn't yet on her deathbed, but the news that her her children and grandchildren have been warned to prepare for the worst is certainly discouraging.
Of course, until that report is confirmed by palace officials, it will remain mere speculation.
Reports of the Queen's failing health have surfaced on several occasions in the past, and while there may have been genuine cause for concern, she's persevered each time.
Thus far, representatives for the Royals have declined to comment.
Our thoughts go out to the Queen and her loved ones during what appears to be a tremendously difficult time.
We'll have further updates on this developing story as more information becomes available.
