Speaking to Fabulous Digital, body language expert Judi James explains: “Meghan used this gesture when she was wearing her more formal royal clothing for the first time and this implies a desire to look funny and ‘real’ rather than stiff and starchy.
“Princess Diana used to employ similar, self-effacing traits as tie-signs to connect with her fans when she was appearing at very dressy royal events, often grinning and rolling her eyes at the cameras to show she was still natural and down-to-earth despite wearing a long gown and a tiara.”
The former Suits star is due to welcome her first child with Prince Harry next month.
And although the 37-year-old’s due date has not been confirmed, bookies say he or she could arrive on the Queen's birthday, April 21.
"We're just weeks away from welcoming Harry and Meghan's first born into the world, and we could be doing exactly that on the Queen's 93rd birthday,” said Alex Apati of Ladbrokes.
