Sarah Ferguson recently made a shocking confession about her future son-in-law.

The Duchess of York recently spoke with "One Show" about her relationship with Princess Eugenie’s soon-to-be husband. According to Ferguson, they will get along well because they have the same love for a particular alcoholic drink.

"[I will] be the best mother-in-law," Ferguson said (via Daily Star). "The best – the good news is Jack also works as the European Manager for Casamigos Tequila, so I am perfect."

Ferguson also shared that Brooksbank brought some laughter to their household as he shares the same name as their family dog. "Andrew is brilliant because he says 'Jack! Get off that chair!' – so son-in-law Jack jumps up going 'ahhhh god – what have I done now?'" Ferguson continued.

Princess Eugenie’s mom also left her future son-in-law with a word of advice. "The thing about Andrew and I is that we go with our hearts, we go with family unity – we really believe in that," Ferguson added. "You can see that – the York Family unity and it is all about just seeing the light in life and Jack is an amazing bringer of light, and he brings joy."

In related news, the Duchess of York was photographed leaving Mark's Club, a private member's club, in Mayfair London on Thursday night. During the sighting, Ferguson wore a fitting short black dress with a bright orange double-breasted blazer which she left open. Prince Andrew's ex-wife looked calm and happy in her make-up free look as she exited the nightclub.

The duchess opted to go bare legs under her dress which was just appropriate for the summer heat. She paired her wardrobe with her favorite flat black Pretty Ballerinas loafers. She accessorized her get up with a gold locket style necklace, gold hoop earrings, black handbag and an orange pom pom to match her blazer.

Ferguson has just returned from Nepal. The mother of two is very busy with her charity and with Princess Eugenie's royal wedding, where she was reportedly very involved. The Duke and Duchess of York are reportedly working together for the wedding reception.

"Sarah and Andrew are helping to organise the evening party," a source told Vanity Fair. "The plan is for a marquee to be set up in the grounds and dancing late into the night."
