All eyes were on the royal family as they joined the Queen on the balcony for her Platinum Jubilee Trooping the Colour - especially Meghan Markle, who reunited with her in-laws for the occasion.
While many were concerned it could be awkward following months of frosty relations between the Sussexes and The Firm, especially since their infamous interview with Oprah Winfrey, a body language expert believes that was far from the case.
While she wasn't part of the official part of the event, she did watch proceedings from the Duke of Wellington’s former office alongside other, less senior royals.
Speaking to The Mirror, Judi James claims Meghan was "in her element" as she chatted to the Tindall and Phillips children.

She was spotted leaning down to chat with them, jokingly shushing with them while the procession took place outside.
She said: "Glimpsed from a window we could see Meghan and Harry looking unexpectedly relaxed and upbeat in a low-key appearance that seemed much more to their tastes than previous awkward, tense appearances with the rest of the Firm.
"Meghan was looking playful and in her element with a group of young royals who also seemed to adore her, shushing them with her eyes wide and rounded but also smiling and she shushed to suggest she wasn’t being totally serious.
"Her loving gaze at Harry created some solid continuity with the more public PDAs the couple are famous for and the fun they were having looked a world away from some of the more tense-looking poses from the top level royals out on the balcony as they "watched the fly-past."
However Judi believes it was a very different story when it came to the Duchess of Cambridge, who did made the cut for the historical Buckingham Palace balcony moment.
She was joined by Prince William and her children Prince George, Princess Charlotte and Prince Louis to watch the RAF flypast, but Judi believes she looked far more "serious" than her sister-in-law.
Judi said: " William and Kate emerged wearing their serious facial expressions, with William directing their children into position before standing apart from Kate to ensure a good spread of parental guidance."
Meghan and Harry have returned to the UK as a family for the first time since quitting in 2020. They've been back once as a couple, making a secret visit to the Queen ahead of the Invictus Games, and Harry returned alone for Prince Philip's funeral and the unveiling of a Princess Diana statue.
It's the first time their daughter Lilibet has visited her father's homeland and met her royal family. She will celebrate her first birthday on Saturday, with the Queen expected to attend her party.
