Melania Trump, the incoming First Lady of the United States, has an "air of relaxed confidence" about her.

At least, this is what body language experts are saying, according to the Daily Mail.

This comes after Mrs. Trump, this past week, participated in some interviews, including one on the Fox News Channel.

Body language experts are suggesting, based on what they saw in the interview, that something has changed about Mrs. Trump since the last time she was the first lady.

What is it?

According to body language expert Judi James, who spoke with the Daily Mail, what Mrs. Trump has - that she did not necessarily have last time around - is a certain confidence.

James said:

Her overall pose suggests an air of relaxed confidence that she seemed to acquire during and after the launch of her book, when she appeared as a star name in her own right rather than just as wife of the President.

James is referring to Mrs. Trump's memoir, Melania, which recently came out and has since become a New York Times number one bestseller. The book is billed as "a compelling and inspirational memoir that offers a glimpse into the life of a remarkable woman who has navigated challenges with grace and determination."

Speaking with the Daily Mail, James went on to suggest that "Some of the rigidity had gone from [Mrs. Trump's] body language and her smile looks richer, more ready and more natural."

James added:

Her hands are gently folded in her lap here, signaling higher levels of confidence, and her single gesticulation of raising one hand with the fingers slightly splayed, shows a desire to communicate that she tended to reserve for formal speeches previously. She seems to be enjoying what might actually feel like the power of a new double act with her son Barron that leaves her less dependent on her double act with her husband.

So, what is going on?

Admittedly, we can only speculate about what may or may not be going on with the incoming first lady. But, perhaps, Mrs. Trump herself explained the situation during her interview.

During the Fox interview, she explained that things are very different this time around, as she and her husband get ready to reenter the White House.

Mrs. Trump said:

You know what you need to establish, you know what kind of people you need to hire for your office.

She also went on to say that, because she and her husband already know how to handle the situation, they are setting things up so that they can hit the ground running on day one of their new administration.

It is about six weeks away from Trump's inauguration.
