Sarah Ferguson was actually dating another man when she became interested in Prince Andrew. And according to her late mother, the Duchess of York’s relationship with the playboy prince changed her life.

In the book “Sarah: HRH The Duchess of York,” royal author Ingrid Seward spoked with Ferguson’s mom, who said that her daughter’s relationship with Prince Andrew just got better and better.

“It completely changed Sarah because it had none of those breakups and dramas. The more she got to know him, the better it became,” she said.

Prior to dating Prince Andrew, Ferguson was in a relationship with a much older businessman named Paddy McNally. But by the looks of it, the mom of two’s relationship was not as peaceful as her relationship with Prince Andrew during its first few years.

Seward revealed that just after six months of knowing each other, the Duke and Duchess of York fell in love, and they decided to get engaged. Fergie wanted to tell all of her friends that she will soon be marrying the royal because she was madly in love with him.

However, Prince Andrew wasn’t afforded the same right because he couldn’t make his engagement public until after he has asked for his mom’s permission.

“By law, Andrew could tell no one until he had officially asked permission of the Queen and obtained her consent to marry – and the Queen and the Duke of Edinburgh were not due back from their tour of Australia and New Zealand for another three weeks,” Seward said.

But in the end, the Queen gave Prince Andrew her blessing to marry Ferguson. After all, Her Majesty actually liked Ferguson in the beginning.

“Their mutual employment of country pursuits, their love of dogs and horses, provided them with a common ground. The Queen Mother liked her at once… She thought Sarah would be ideal for Andrew,” Seward said.

Prince Andrew and Ferguson tied the knot at Westminster Abbey on July 23, 1986.
