A lip reader has suggested Princess Beatrice and Eugenie vowed "we're in this together" as their father, Andrew Mountbatten-Windsor, was stripped of his titles.
The pair were seen in Mayfair, London, as they embraced in an intense hug and engaged in dialogue.
In their first public appearance since their father was publicly stripped of his titles, lip reader Nicola Hickling claims Princess Beatrice, 37, mouthed to her younger sister: "We’re in this together, don’t forget that".
Speaking to the Daily Mail, Ms Hickling suggested the 37-year-old told her sister "it's going to get harder" and "we can't do anything".

Andrew, 65, has been ousted from Royal Lodge amid scrutiny about his ties with convicted paedophile Jeffrey Epstein.
The former prince has consistently denied all allegations linked to Epstein, with the Metropolitan Police previously ruling that the sexual assault claims against him were insufficient to warrant further investigation.
Beatrice and Eugenie have returned to work since the scandal surrounding their father, with the pair both retaining their princess titles and membership in the "House of York".

Princess Beatrice made her return to UK charitable duties, touring medical research facilities at Chelsea and Westminster Hospital in her capacity as patron of Borne.
Her visit to the hospital carried deep personal meaning for the princess, whose daughter Athena Mapelli Mozzi arrived several weeks early in January, weighing just four pounds and five ounces.
In written reflections about the experience, Beatrice revealed that her newborn was "so tiny it took more than a few weeks for the tears of relief to dry".
During her tour around the laboratory, she said: "The work that Borne is undertaking is something that is incredibly close and personal to me following the early arrival of my second daughter.

"As a patron of Borne, I am so grateful for the scientists and clinicians who took the time today to show me the advances they are making to reduce the risks to expectant mums and babies."
Elsewhere in London, Eugenie supported the King's Foundation in her role as a mentor for its 35 under 35 network.
