Princess Eugenie and Jack Brooksbank’s body language says a lot about their relationship.

Judi James, a body language expert, analyzed the couple’s engagement interview with BBC earlier this year. She described Princess Eugenie as sexy and Brooksbank as shy.

“Eugenie and Jack smiled openly almost non-stop through their interview and many of the smiles looked impossible to repress, which is often a symptom of the rather bashful early stages of love. Jack, in particular, wore kind of the rounded and raised cheeks that signal genuine happiness and at times his cheeks even turned pink to show shyness too,” James told Express.

The body language expert also said that the 28-year-old princess appeared more self-assured in front of the camera perhaps due to the fact that she grew up in front of the press.

“Eugenie’s rather husky, sexy voice and her more assured body language suggests she will be the more powerful partner although she used several lowering signals to make her fiancé feel more dominant, like tilting her head towards his chest, touching her own hand to her chest in a gesture of coyness and even bending her knees as she laughed or spoke to self-diminish,” she explained.

Meanwhile, James said that Brooksbank’s body language is quite different from Prince Andrew and Prince Harry.

“Eugenie and Jack’s body language shows a younger couple rather sweetly in love, especially Jack who lacks the signals of alpha machismo that Andrew and Harry learned in the forces. Jack stood square to the interviewer with his arms rather self-consciously straight to his sides and the biggest PDA of this interview was the joined hands with meshed fingers that showed mutual levels of love and reassurance,” she said.

Princess Eugenie and Brooksbank will tie the knot on Oct. 12 at St. George’s Chapel in Windsor Castle.
