When she's not on official trips or appearances, Melania Trump is a very private woman. 

Body language experts however, might have some insight as to what goes on behind the gaze that gives nothing away. 

After appearing to avoid holding her husband's hand, people have been feverishly theorising about Melania's true feeling towards Donald. But what about the First Lady's thoughts about her husband's daughter, Ivanka? 

Speaking to the Express, body language expert Judi James claims that prior to the White House both women flanked the President like "bookends":

"The look seemed to have the objective of raising his alpha profile and both women seemed to play along, complimenting his all-powerful male look by posing like beauty pageant queens."

But the presidency has introduced a new dynamic according to James, who added:

"[Melania is] following in the footsteps of one of the most charismatic First Ladies ever, while Ivanka plays the role of King's Hand, chief support, adviser and even stand-in at world leadership occasions.

The role of First Lady seems to have driven Melania into a Mount Rushmore-esque stony facial expression at times and those times are often when she is around her step-daughter Ivanka."

This makes Melania appear frostier than Ivanka, whose facial expressions are friendlier-looking.

Speaking to independent.ie, body language Tracey Cox pointed out that Ivanka and Melania do not look completely comfortable with one another. 

After pictures of Melania appearing to look sad at the inauguration went viral, most suspected that she was unhappy in her marriage.

But a few amateur body language detectives think that she was put out by Trump ignoring her in favour of his daughter.

Whether you trust the body language experts or not, we can all agree the Trumps are fascinating to observe.
