The Duchess of York is said to have rekindled her romance with her former husband, the Duke of York.
Friends claim the couple are so close that they will eventually formalise their reunion.
"Mark my words, they will remarry," said one friend. "It is only a matter of time."
Another said: "It wouldn't surprise me at all. They are a wonderful couple together and, better still, pretty amazing parents."
The couple have remained close since they divorced in 1996 and both live at Royal Lodge, the former country home of the late Queen Mother, in Berkshire. They joined their children, Princess Beatrice, 25, and Princess Eugenie, 23, for the weekend at Balmoral, the Queen's Scottish retreat, this month.
