The Queen's marriage to her beloved husband Prince Philip lasted more than 73 years until his death last year at the age of 99.
In his final months, Philip spent his time at Windsor Castle with his wife and a select number of staff as they shielded from Covid-19 in what was dubbed HMS Bubble.
According to a royal aide, during this time the couple would regularly lovingly bicker - like any other long-married couple.
But they added that despite their enduring marriage - the Queen would let Philip know that they weren't just any normal couple.
That's because on one occasion, Philip was overheard telling his wife of 73 years "Oh, do shut up, you silly woman", an unnamed palace aide told the Daily Mail.
And the Queen allegedly said back straight away: "I am not a silly woman, I am the Queen."
The aide added: "They bickered with one another. It was sweet but so unexpected.
"I couldn't believe my ears but I was told this was how they always were with one another."

Later this month the Queen and other members of the Royal Family are expected to attend a memorial service of thanksgiving for Philip. It is set to take place at Westminster Abbey on March 29.
It comes as the Queen recovers from contracting Covid - although it is thought she is now much better after suffering mild cold-like symptoms.
Yesterday, she had been down to attend a diplomatic reception at Windsor Castle, where she would have met hundreds of members of the Diplomatic Corps.
However, on Saturday it was announced the event was being postponed following advice from the Foreign Secretary.
It is understood this is down to the situation in Ukraine and Russia.
Until recently the Queen had been on doctors’ orders to rest since mid-October, after cancelling a run of engagements and spending a night in hospital.
She regularly uses a walking stick and has been pictured recently looking frail. She has spoken of her mobility issues, telling two senior military officers during a Windsor Castle audience last week: “Well, as you can see, I can’t move.”
