But, while many have pondered whether they’re more than friends, Sarah insisted they were not a couple in a past interview.

But, would it take the stars to align for Prince Andrew and the Duchess to get back together?

According to Astrology.com, the duo rekindling their romance may not be totally implausible.

That’s because, when it comes to the two royals’ star signs, the website claims they are “very compatible”.

Born on February 19, the Duke’s Zodiac sign is Pisces.

Meanwhile, Sarah, whose birthday is October 15, is a Libra.

“When Libra and Pisces come together in a love affair, theirs is a congenial and even-tempered romance,” the love compatibility analysis explains.

“These two Signs are very compatible, making for a truly smooth-sailing love affair.”

Another suggestion about the two star signs reads: “Libra and Pisces make great friends as well as lovers.

“They understand one another: Both can be indecisive and tend to work in multiple directions at once.”

Yesterday, Sarah was forced to deny rumours that she and Prince Andrew could be back together – following their Bahrain trip.

A spokesperson for the Duchess said: “The Duke and Duchess of York continue to be good friends and nothing has changed in their relationship.”

Meanwhile, a senior Palace source told the Mirror: “While [the] Duke and Duchess are not officially back together, it is fair to say their relationship is incredibly strong.

“The two of them are not involved in relationships with anyone else, which of course likely to fuel rumours of an unlikely reunion.

“They very much enjoy each other’s company and their public displays of affection for one another are becoming more frequent.”

The parents-of-two were joined not only by Princess Beatrice, but also her boyfriend Edoardo Mapelli Mozzi.

The Princess recently confirmed her relationship with the 34-year-old, who is also known as Edo.
