Sophie, Countess of Wessex, recently shared an anecdote about Queen Elizabeth II and her daughter, Lady Louise.

During an interview with journalist Rhiannon Mills for Sky News, Sophie said that it was only after Lady Louise went to school that she realized how closely related she was to the British monarch.

There was one instance wherein Lady Louise went back home from school, and she told Sophie how her classmates said that her grandmother and the Queen are one and the same person. Sophie told her daughter that her classmates were correct, but the young girl still did not understand how her grandmother could be the Queen.

Meanwhile, Prince Edward was also asked the first time he worked out the role that his mom played in the wider society.

“I can’t necessarily remember when that realization was there because when you grow up intuit family and in that environment, that’s just what your parents do. It’s been much more interesting watching our children growing up and watching our children trying to work out what this is and how that works… I was probably not until 5 or 6, I think,” he said.

The couple’s revelations about Her Majesty and Lady Louise came just days after it was revealed that Sophie is one of the Queen’s favorite royals. Neil Sean, a royal expert, told Today that the Queen adores Sophie. A source also told Daily Mail that the Queen trusts the mom of two.

“She is trusted and relied on by the Queen in a way I couldn’t say applied to the Duchess of Cambridge or the Duchess of Cornwall. She is like another daughter to Her Majesty, they are that close,” the source said.

In the past, Sophie and the Queen have been photographed together in public. There was one Christmas when they arrived in church together in Sandringham. But when it comes to the monarch’s favorite child, the title still belongs to Prince Andrew.
