While the coronavirus has got in the way of many events, both Sophie and Kate have been delighting fans with virtual appearances.
Last month, the royals appeared together as they spoke to healthcare professionals via video chat.
In the past, before the lockdown began, Sophie and Kate have attended many events together with the Royal Family.
When Kate joined the family, Sophie may have given the young royal some guidance, according to body language expert Judi James.
Sophie seemed to merge into royal life easily which could have been copied by the Duchess of Cambridge.
Judi told Express.co.uk: “When Sophie married Edward she was hailed as the new Diana.
“But what followed looked like a masterclass in hunkering in as the soap-opera-free royal bride who managed to be a stabilising influence on her husband while keeping press and royal fan attention to a minimum.
“Sophie is also said to be a close ally of her mother-in-law the Queen and in terms of her body language she tends to blend some of the signals of the kind of laid-back calm and fun that we get from Zara Tindall with the stoic, deft formality of the Queen herself.”
When they have attended events together, Sophie has looked happy to help Kate and taken on an almost maternal role, the expert claimed.
Judi explained: “Many of the poses of the two women together show Sophie face-checking Kate with quite strong bouts of watchful-looking eye contact to suggest she’s taking a semi-maternal approach.
“However, she also has raised brows and what’s called a ‘pinging’ smile that implies she wants to ensure Kate is enjoying herself.
“There is some mirroring when the two women walk together but it’s primarily Sophie projecting the stronger signals of relaxed confidence while Kate smiles happily at her side.”

How did Kate Middleton become a royal?
Kate Middleton, or Catherine, Duchess of Cambridge, was born on 9 January 1982 at the Royal Berkshire Hospital, Reading, England.
She was born to Michael and Carole Middleton, a former flight dispatcher and air hostess. The couple founded a party supplies company, Party Pieces, in 1987 – now estimated to be worth £30 million.
Kate has a younger sister Pippa Matthews, 34, and a younger brother James Middleton, 31.
Kate and her family moved to Amman, Jordan, in 1984, where the future Duchess was educated at an English-speaking nursery school.
After moving back to Berkshire the family sent Kate to private school, St Andrews School. She went on to briefly study at Downe House before moving onto Marlborough College where she boarded.
For university the young Kate attended the University of St Andrews in Fife, Scotland. Here she was awarded an undergraduate MA (2:1 Hons) in history of art.
Relationship with Prince William
Kate met Prince William when they were both studying at St Andrews, and both living in St Salvator’s Hall. Famously, William reportedly took a fancy to Kate after she wore a see-through dress during a fashion show.
In 2003 the couple began dating and lived together during their second year of university.
The couple split in April 2007, however, in October they were back together.
Prince William proposed to Kate Middleton with his late mother Princess Diana’s engagement ring in October 2010. The couple were holidaying in Kenya at the time.
On 29 April 2011 they married at Westminster Abbey with a whopping 26 million watching the event live.
Kate wore an Alexander McQueen dress worth a reported £250,000 on the big day.
Kate assumed the title “Her Royal Highness The Duchess of Cambridge” and also become the Duchess of Cambridge on the day.
