Princess Eugenie is marrying a man who is very different from her dad, Prince Andrew.

Prince Andrew and Sarah Ferguson's daughter is the next royal bride. Prior to her big day, body language expert, Judi James, examined her husband-to-be's actions and noticed that it's opposite to that of the Duke of York.

"Jack's body language is almost totally opposite to Andrew's at that point in their relationships," James told Express.

According to the expert, Brooksbank is more amicable during his interview compared to Prince Andrew during his engagement interview with Ferguson.

"There is no arrogance from Jack and his raised brows and beaming smile make him look amenable and smitten rather than difficult and high-status," James added.

While Brooksbank is different from Prince Andrew, James likened Princess Eugenie's groom to Captain Mark Phillips. According to her, the two gentlemen share similar signals.

"(Jack’s) amiability signals look rather similar to Captain Mark Phillips' when he married into the royal family but unlike Mark it could be that Jack is given an royal induction, being welcomed by a much more empathetic and less intimidating generation of younger royals," James added.

In related news, the Duchess of York said earlier that she will be the best mother-in-law to Brooksbank as they share the same fondness for a particular drink - tequila.

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

Ferguson also shared a funny moment about Brooksbank and how he brought confusion in their household since 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 said.

Princess Eugenie and Brooksbank are tying the knot on Oct. 12 at St. George's Chapel at Windsor Castle. Just like Prince Harry and Meghan Markle's nuptials, the couple will also have a horse-carriage procession after their ceremony.

Katie Hind also noted that the upcoming wedding might include its own family drama. There are speculations that Prince Philip and Ferguson's rift may cause friction during the celebration.
