The Duke of York and his ex-wife, Sarah, Duchess of York, are staying at Balmoral Castle for a short vacation with The Queen.
In a further sign that Her Majesty has welcomed Sarah back into the family, she and Prince Andrew are expected to stay in the Scottish residence for a week or more.
It is no coincidence, however, that when Sarah is at Balmoral or another royal residence, the Duke of Edinburgh is nowhere to be seen.
Royal diaries are scheduled months in advance, and every year the duchess arrives and departs before the Duke of Edinburgh resides.
After her marriage to the Royal Family in 1986 at Westminster Abbey, the duchess spent six years as a civilian working royal, before being placed on what would be called "leave" of royal duties after her separation in 1992.
The Duke and Duchess divorced in 1996. As the Princess of Wales after her divorce, Sarah was allowed to retain "Duchess of York" as a courtesy title. The couple has two children together, Princess Beatrice and Princess Eugenie.
Although divorced, the couple remains incredibly close and have been fully united in their children's education.
In an extensive interview with the Daily Mail last year, the duchess was asked if she and Andrew might one day tie the knot.
She said: "So many people have asked me, but we are as happy with the way we are now.
"We enjoy each other's company; we allow each other to blossom. I know it's like a fairy, but so are we."
Interestingly, Sarah refused to dismiss the prospect of a rematch, which will undoubtedly lead to more speculation
However, she said she and Andrew were no longer a couple.
The 59-year-old said: "We are the happiest divorced couple in the world. We divorced each other, not each other."
"July 23, 1986 was the happiest day of my life. Andrew is the best man I know. What he does for Britain is incredible; nobody knows how he works for his country.
"It is my duty to him. I am so proud of him. I stand by him and always will. As we are he is our fairy."
