Prince Andrew has sparked rumors that he and Sarah Ferguson are getting back together following this sweet gesture.

The dad of two paid tribute to his ex-wife on her birthday on Monday, Oct. 15. Prince Andrew uploaded a photo of Ferguson in her blue dress and jacket on his Twitter account.

“Happy birthday to @SarahTheDuchess. Wishing you a very happy day!” he captioned the snap.

Ferguson shared the same snap on her Instagram account and revealed that her dress was created by Emanuel Ungaro and Jad Ghandour.

Prince Andrew and Ferguson have been sparking reunion rumors ever since it was reported that they are working together in hosting Princess Eugenie’s wedding reception. On their daughter’s wedding day, the ex-couple also sat beside each other in the front row of St. George’s Chapel in Windsor Castle.

After Princess Eugenie and Jack Brooksbank’s official wedding photos were released, it was also evident that Ferguson and Prince Andrew have a close relationship with each other. The ex-couple didn’t seem awkward at all when they posed beside each other.

But while inside the chapel, it was also evident that they didn’t act lovey-dovey. Both Prince Andrew and Ferguson acted seriously and were focused on their youngest daughter.

Following Prince Andrew’s sweet birthday tribute for the Duchess of York, Isabella Sullivan, a journalist for Express, claimed that it is possible for the ex-couple to celebrate Ferguson’s birthday together. After all, Ferguson still lives with Prince Andrew at the Royal Lodge in Windsor.

Prince Andrew and Ferguson divorced in 1996 after 10 years of marriage. The mom of two previously revealed that Prince Andrew’s busy schedule was one of the reasons why their relationship failed. She also admitted that her desire to work was another reason why they decided to get a divorce.

“I wanted to work; it’s not right for a princess of the royal house to be commercial, so Andrew and I decided to make the divorce official so I could go off and get a job,” she said (via Harper’s Bazaar).
