They were spotted "getting cosy" at Lady Gabriella Windsor's wedding and Sarah Ferguson all but confirmed she's set to marry Prince Andrew for the second time when she was snapped beaming alongside a lavish lace wedding gown!
Fergie, 59, was pictured at a pop-up bridal boutique in the UK on May 19 looking visibly smitten with a gorgeous long-sleeved dress and accompanying veil.
The store donates proceeds to good causes from the sale of its designer dresses, which Fergie confessed "moved" her – and the duchess reportedly took the opportunity to browse for an outfit in which she can say "I do" to her royal ex.
"Fergie and Andrew are back together and they want to make it official," a royal insider confirms to Woman's Day. "They've never stopped loving each other and through all their trials and tribulations they've come out the other side stronger than ever."

The close bond between the exes – parents to Princesses Eugenie and Beatrice – has long been known, with Fergie revealing that she and Prince Andrew "never really left each other" despite their divorce.
Sources say the pair looked like "a new couple" at the wedding and their reunion has been largely welcomed by the royal family.
"There was so much passion and laughter between them, it was very sweet," the source adds.
