The British Royal Family has a lot of members, especially when the extended families of the Saxe-Coburg and Gotha clan are counted. While the majority of the news and reports largely talk about the Windsor clan alone when referring to the Royal Family, other members have remained close to the main royals. More often than not, these members, include especially Queen Elizabeth II's cousin, Princess Alexandra.

According to the official website of the royals, the Princess is a "working" royal. This is why she has been almost always present in various official engagements with the Queen.

When she was born in 1936, she was the sixth person in line to the throne. But, since the Windsor clan has become a lot more expanded today, she is now the 53rd person in the line of succession.

Despite the position to the British Monarchy, Queen Elizabeth II and Princess Alexandra reportedly share a very close relationship since they were kids. However, recent reports revealed that the monarch's cousin once described her son, Prince Charles as "gruesome."

As per 9Honey, the then-15-year-old Princess wrote a letter to her brother, Prince Edward. Using an official royal paper that came with a stamp of the Balmoral Castle, she reportedly wrote and shared a moment that happened between her and the Heir Apparent.

At the time of the writing, the Prince of Wales was only four. Princess Alexandra told her brother that the Queen's son was fond of watching her "blistered lips" pierced by a doctor that came one morning.

As it happened, the then-teenage Princess was playing with the other guests and ended up getting hurt, which caused her lips to develop blisters. She shared that Queen Elizabeth II's first son also "insisted" on watching what the doctor had to do with her lips during the visit as he was "fascinated" by it.

Princess Alexandra then rhetorically wrote to Prince Edward that Prince Charles is a "gruesome" child. While it may seem off to read at first, the tone of the letter seemed fun and lively. Not to mention, the Princess was just a teenager at that time, who appeared to be very excited about sharing her stories with her brother.

In a similar report by The Telegraph, the letter in question was sold in an auction many decades later. It was revealed that the letter was dated 1952, which also contained Princess Alexandra's stories about her experiences while staying with Queen Elizabeth II and the rest of her family.
