The two royals are currently at Windsor Castle, where they are sitting out England’s second national lockdown. Earlier, they had spent a period of time in Sandringham following the Queen’s annual summer break at Balmoral.
Now, royal commentator Katie Nicholl has said she thinks the couple have “rediscovered some of the happiness of their earlier years” because of the time they have spent in each other’s company.
Speaking to Nine news, she said the Queen has still been “working very hard every day” despite not taking guests or audiences.
Ms Nicholl also supposed the monarch would have breakfast and lunch alone.
But she added: “I know for a fact there were quite a few occasions where they made a point of coming together for dinner at the end of the evening, dressing up and being at the dinner table, which probably hasn’t been the case for quite a long time.”
According to the royal analyst, who cited a “very well-placed source”, the Queen was “very down about the pandemic” at points because she wasn’t able to work as usual.
However, she said spending more time with her husband was a “real upside for her”.

They marked the occasion by sharing a photograph of them opening a card that had been sent by the children of the Duke and Duchess of Cambridge.
While the Queen is reportedly feeling “down” about lockdown restrictions, the monarch has still managed to get outdoors this year.
On one occasion, she was spotted riding a horse on the grounds of Windsor, back in June.
A photograph shows the Queen, 94, smiling as she sits atop a 14-year old Fell Pony called Balmoral Fern.
According to the BBC at the time, the monarch regularly rides on the ground of Windsor, where she was then isolating.
Before then, the last public photo of the Queen was taken on March 19. She was seen in a car being driven away from Buckingham Palace to her residence in Berkshire.
Since then, the Queen has left her residences altogether on public appearances.
In October, she joined Prince William on what was her first public engagement since March.
The two royals ventured to Salisbury where they visited the Defence Science and Technology Laboratory.
There, they met scientists involved in the nation’s Covid-19 response and also opened a new Energetics Analysis Centre.
