Meghan Markle - now the Duchess of Sussex - is known for her enviably long and luscious hair.
So perhaps it's no surprise that the wife of Prince Harry is wont to flick it from time to time.
But according to Australian body language expert Louise Mahler - who studied Meghan during her appearance at the official opening of the ANZAC memorial in Sydney's Hyde Park on Oct.20 - there is more to Meghan's hair flick than meets the eye.
According to Louise, Meghan was "trying to take a back seat and not be noticed" at Saturday morning's event.
"She is playing a role of the 2nd fiddle," the expert told New Idea.
"I don’t know she is that comfortable in that role."
Louise went on to say that Meghan's hair says a lot about her
"Meghan’s “tell" is her hair," Louise said.
"Whenever she is thinking or changing direction or uncertain, her left hand goes to her hair."
Louise went on to say the move can be seen as one of "weakness".
"However, she is beautifully doing what is expected of her," Louise went on.
"Well done Meghan. Her heart is in the job."
