Prince Edward and his wife Sophie have been spotted out and about in St Andrews, where The Crown is currently filming.
The sixth and final series in the royal saga is filming at the Scottish university, where 40-year-old Prince William met his now-wife Kate Middleton in the early 2000s.
And while pictures of the set and cast were shared, very few seemed to catch a glimpse of Edward and Sophie, now the Duke and Duchess of Edinburgh, as they casually walked around the grounds.
In a video taken by Adam Thomson, the royal couple can be seen casually walking near the set. Adam told FEMAIL that the couple were so low-key that he didn’t realize who he was looking at at first.
He explained, “We saw them turn the corner, and it was kind of a surprise because at first we thought they were actors, but then we realized they were actually (Edward and Sophie).”

Adam added that despite seeing several of what he thought were professional photographers, none of them seemed to see the Edinburghs.
According to Adam, the royal couple was “right next door” to the film set where he saw them.
The cast members were also photographed while filming the actual drama. Meg Bellamy became Kate Middleton while Ed McVey was seen portraying prince william while the series recreated their time in St Andrews, where they met and fell in love.
Theatre-trained 22-year-old Ed, who will play Prince William during his teens and early twenties, was seen wearing a navy puffer jacket for the scenes.
Meanwhile, 19-year-old Meg was photographed wearing a brown fleece as she walked around the set, her brown hair styled in loose waves.
Prince William and Kate became friends in their first year before romance blossomed after William saw ‘hot’ Kate strutting around a charity fashion show in a see-through dress.
She had moved to the prestigious Fife university after completing her studies at Eton College in 2001. They graduated in 2005, and William proposed five years later.
The sighting comes as the new Duke and Duchess of Edinburgh are in Scotland for a visit.

The Crown film crew sets up shop at the University of St Andrews, where Prince Edward and his wife Sophie were seen.
On Friday, the couple greeted crowds on Edinburgh’s Royal Mile and visited the City Chambers to mark one year since the city’s formal response to the invasion of ukraine.
Edward, who was bestowed the title of Duke of Edinburgh on his 59th birthday on March 10, was speaking to an enthusiastic audience when he seemed to lose his voice with emotion when referring to his wife, now Duchess of Edinburgh.
As the new duke celebrated his birthday, his older brother, King Charles, bestowed on him the new title in accordance with the wishes of their late father, Prince Philip.
He told the crowd that the day had been “very special and a bit overwhelming” for him and his wife, “the Duchess.”
Addressing the audience, he said: “Thank you so much for welcoming us to Edinburgh today on a very special and slightly overwhelming day for, now, my wife, the Duchess.”
As she addressed Sophie, 58, with her new title, her voice rose slightly with excitement.
In response, the crowd laughed at her innocent and childish glee and clapped while smiling.
Sophie’s previous rank as Countess of Wessex meant that she held the same rank as her husband Prince Edward, the Earl of Wessex.
This rise in royal status for 58-year-old Sophie is a touching tribute to the late Queen’s daughter-in-law, who affectionately called her ‘Mum’.
Married to Prince Edward for 24 years, she is well known for her down-to-earth nature and was considered by the late Queen to be the safest pair of hands in The Firm.

However, their new titles of duke and duchess have a higher rank, raising them in status to just below the monarch.
Duchesses are also known as Her Royal Highness. Meanwhile, the title of Duke and Duchess of Edinburgh is one of the oldest in the Royal Family.
The move is a touching and enduring connection between the late Queen and her much-loved daughter-in-law, Sophie.
She was known as the “favorite” family member of the late monarch and his closest confidant.
Experts previously noted that the Countess being in the spotlight is what Prince Philip “would have wanted” and helped “keep her memory alive.”
