Princess Beatrice, 33, recently tweeted to share footage of herself attending an event for Forget Me Not Children’s Hospice, and body language expert claims the royal showed signs of ‘distress’ upon leaving . The Forget Me Not Children Hospice provides support for children whose lives are cut short and their families, and Beatrice attended a special garden party last week to celebrate the 10th anniversary of the construction of Russell House.

Beatrice is the Royal Patron of the Hospice and officially opened the purpose-built Russell House Foundation property in 2012.

The foundation shared footage of the celebrations, showing the beaming princess wearing a belted coat that accentuated her plump belly as she helped bury a time capsule to mark the occasion.

However, despite her smiling appearance, an expert claims that the pregnant royal’s body language in the pictures reveals reasons why “she cannot reflect total happiness.”

Body language expert Dr Lillian Glass said Express.co.uk: “She has a strained smile and it looks like she has a lot of tension on her face in general.

“She doesn’t show a real smile of squinted eyes and uplifted cheeks.”

When asked the reasoning behind that phrase, Dr Glass says the royal could be affected by the scandal involving his father, Prince Andrew.

The expert refers to the ongoing civil lawsuit facing the Duke of York as he is being sued for unspecified damages by Virginia Giuffre, formerly known as Virginia Roberts.

Ms Giuffre filed a civil lawsuit against the 61-year-old Duke under the “US Child Victims Act” claiming that she was “trafficked against him and sexually assaulted by him” when she was 17.

The ongoing sexual abuse allegations could have a ripple effect on Prince Andrew and Sarah Ferguson’s eldest daughter, according to Dr Glass, and could even cause her to “embarrass” or “eclipse” her pregnancy, which ‘she describes as “a happy event”.

She said: “While she may be happy with her unborn baby, the fact that her father is in the spotlight so negatively on a constant basis must add to her emotional distress and pain and create embarrassment. and this burden can eclipse its happy an event.

“Maybe that’s why she can’t reflect total happiness.”

Despite the civil lawsuit, the Queen’s granddaughter was seen interacting with children, ahead of the birth of her firstborn in the fall.

At the event, she posed alongside the families, supporters, staff and volunteers who also attended.

She was also spotted leaving The Arts Club in Mayfair on Tuesday night wearing a black minidress that accentuated her baby bump.

Princess Beatrice announced in May that she was pregnant with her first child, who will be the Queen’s 12th great-grandchild.

The announcement came less than 12 months after having tied the knot with real estate developer Edoardo Mapelli Mozzi.
