'We go with our hearts': Sarah Ferguson gives rare insight into her close bond with Prince Andrew

Sarah Ferguson, Duchess of York, has opened up in a rare TV interview with BBC's The One Show, shedding light on her relationship with Prince Andrew and how the family is preparing for daughter Eugenie's wedding to her fiance Jack Brooksbank.

The Duchess, speaking to hosts Alex Jones and Michael Ball, was discussing Jack and Eugenie's upcoming 12th October nuptials - when she reflected on her and Andrew's own relationship.

When asked if she'd given Jack any advice about entering into the royal family, Sarah Ferguson revealed that when she and Andrew married, and to this day, they have always shared a positive mantra for life.

Fergie went on to suggest that like her parents, Eugenie, and Jack, appear to share similar values.

She confessed, "The thing about Andrew and I is that we go with our hearts. We go with the family unity, we really believe in that. And you can see that.

"It's all about seeing the light in life, and Jack really is a bringer of light."

The Duchess of York went on to share a sweet insight into life in the York family - revealing that the foursome often joke with Jack for sharing his name with their family dog.

She revealed, “This is where Andrew is brilliant, you see, because he says ‘Jack! Get off that chair!’.

“Jack, son-in-law Jack, jumps up and says ‘Argh,what have I done now?’. Then we all said ‘No, not that Jack!’”

Sarah and Andrew, despite divorcing in 1996, still enjoy a very close bond. The former couple often speak about their close relationship, as they continue to bring up their two daughters, Beatrice and Eugenie.

During the interview, Sarah also spoke about the possibility of the family growing.

When asked by Alex Jones whether she thought she'd make a good grandmother, following Jack and Eugenie's wedding, she responded, "Excellent. They are thrilled, because I used to write children’s books, and I am a child, I haven’t grown up."

The Duchess also shed some light on how plans for the big royal wedding are going - revealing that her daughter has everything under control.

She admitted, "Eugenie is very controlled – she is so sorted. She knows exactly what she wants,"

Sarah continued, "Jack and Eugenie are very contemporary, they are very inclusive. And they are all about love, and they want this wedding to be about that – to include everybody and to really absorb the love they have for each other with everybody else."

The Duchess of York went on to reveal that she's been so busy with her 'mother of the bride' duties that she actually hasn't had time to find an outfit for the big day yet.

And when asked whether she thinks she'll be emotional on her daughter's special day, Sarah confessed that she may shed a few tears.

The writer admitted, "I do understand why mothers cry at weddings now. All my life I thought, 'Oh, what’s she crying for?' It’s lovely, it’s a great day."
