When a major person in her life died, Queen Elizabeth II shown some grief. Something that's foreign for any members of the royal family. 

According to Rachel Burchfield, presenter of "Podcast Royal," the Queen, then-Princess Elizabeth, sobbed her heart out when she learned that her father, King George VI, had died. 

She was apparently weeping inside the plane's restroom since she was returning to the United Kingdom, canceling the remainder of her trip to Kenya. 

Tragically, Elizabeth was reputedly the last person to learn of her father's death while on vacation with her husband, Prince Philip, in a remote place.

Burchfield explained, "When she boarded the plane on the way to the UK, it was during the flight, the gravity of her loss hit her. The mask slipped once they were airborne."

But it wasn't just the podcaster who made a claim. 

Even biographer Nicholas Best, founder of "Treetops," previously told The Guardian that then-Princess Elizabeth II left her seat for a while. 

"Her face was set when she returned, but it was obvious to the other passengers that she had been in the loo, having a good long cry."

King George VI died of coronary thrombosis while sleeping on February 6, 1952. 

In Aberdare National Park's Sagana Lodge, Prince Philip and the heir to the throne stayed in a large treehouse.

For a few hours, Elizabeth was unaware of King George VI's death because a telegraph sent to Government House in Nairobi was unable to be understood. 

However, according to writer Granville Roberts, who was covering the couple's royal trip at the time, the devastating news was sent to Prince Philip's secretary, Commander Michael Parker. 

Prince Philip allegedly brought the news to Elizabeth that her father had died during a stroll on the grounds of their residence.

Elizabeth allegedly forbade the photographers from photographing the intimate occasion, according to "Royally Obsessed" host Rachel Bowie.

She said, "In minutes later, I think she climbed up the tree to look up at animals like a princess and came back down like a Queen."

"Immediately arrived letters canceling the remainder of the Royal trip, and then what was really notable about this incident is that no photos were taken on that day, as she had ordered." 

"So, no official picture record from that historic time in those minutes," the presenter said, "but nonetheless, a significant occasion this week."
