Sarah Ferguson, 58, also known as Fergie, told her Instagram followers how “proud” she was of ex husband Prince Andrew, 58, in a gushing post.
She shared an intimate close up photo of Prince Andrew riding as Colonel of the Grenadier Guards.
The Duke of York performed the important role yesterday at the Trooping the Colour parade for the Queen’s official birthday.
Sarah’s gushing post also included two other pictures of Prince Andrew riding as part of the military parade.
She maintains a close relationship with her ex husband and frequently posts about him on social media.
The former royal captioned the image: “Very proud of @hrhthedukeofyork Colonel of the Grenadier Guards #troopingthecolour#beatrice @firstname.lastname@example.org”.
As Sarah is no longer a member of the royal family following her 1996 divorce from Prince Andrew, it is likely she did not attend the parade personally.
Indeed, she appears to have taken the images from television rather than in person, judging by their blurry quality.
However, she is nonetheless regularly on hand to celebrate Prince Andrew – and accompanied the royal to Ascot in the Royal Box last year.
Sarah and Andrew are also anticipating the wedding of daughter Princess Eugenie, 28, later this year on October 12, although it is unknown whether they will be pictured together.
Fans rushed in to respond to Sarah’s gushing post about Prince Andrew, with many calling for the pair to get remarried.
One wrote: “Looking forward to seeing you and Prince Andrew to remarried again….”.
Another wrote: “You have a beautiful family !! When are you and Andrew getting remarried?”/
In the past, Sarah has referred to Prince Andrew as her “handsome prince”.
“He really is still my handsome Prince,” she said of Prince Andrew at Cheltenham Literature Festival in 2013.
However, the pair have never announced any plans to remarry, although there has been much speculation from fans.
Will Sarah Fergsuon and Prince Andrew ever marry again? The birth of the royal baby means there is a chance it could happen, if the pair wanted to.
This is because of a royal law dating back to 1772, known as the Royal Marriages Act, which states the first six individuals in the line of succession to the British throne cannot marry without the king or queen’s consent.
Now that the royal baby of Kate Middleton, 36, and Prince William, 35, has been born, Prince Andrew has dropped from sixth place to seventh place in the line of succession.
This means he is able to marry whomever he chooses without the consent of his mother, Queen Elizabeth II, 92.
