There was more sad news for the royal family as it was revealed that Katharine, the Duchess of Kent, passed away on Friday at the age of 92.
Katharine married Queen Elizabeth's cousin, Prince Edward, the Duke of Kent, in 1961 and became the oldest member of the family when the Monarch died in 2022.
A statement from the Palace confirmed the sad news and paid tribute to the Duchess' great passion for music and charitable work, making special mention of her time spent working with younger people.
It reads: 'It is with deep sorrow that Buckingham Palace announces the death of Her Royal Highness The Duchess of Kent.
'Her Royal Highness passed away peacefully last night at Kensington Palace, surrounded by her family.
'The King and Queen and all Members of The Royal Family join The Duke of Kent, his children and grandchildren in mourning their loss and remembering fondly The Duchess's life-long devotion to all organisations with which she was associated, her passion for music and empathy for young people.
Katharine was a talented pianist, organist and singer who shunned the royal spotlight, going so far as to drop her HRH title, preferring to be referred to as 'Mrs. Kent,' and spending her time teaching music in a primary school in Hull.
Like Princess Kate, she also had a love of tennis and famously consoled a devastated Jana Novotna when she became emotional after losing to Steffi Graf during the women's final at Wimbledon in 1993.
'I just remember from the far side of the net, her face crumpled. It's the natural thing, isn't it? That's what you do when people are crying,' she later recalled the incident.
Katharine was also known for her bold style choices, which included wearing a miniskirt on the eve of her wedding in breach of royal protocol.
She is survived by her husband, the Duke of Kent and their three surviving children, George, Earl of St Andrews, Lady Helen Windsor, and Lord Nicholas Windsor.
The Duchess also suffered a miscarriage in 1975 owing to Rubella and gave birth to a son, Patrick, in 1977, who was stillborn, and chose to speak out about how the experience had a 'devastating effect' on her.
As the news of her passing broke, the Union flag was lowered to half-mast at Buckingham Palace as a mark of respect.
