The First Lady might not be such a big fan of the limelight.

Melania Trump was forcing a positive expression when she was introduced by her husband ahead of his Congressional address, according to an expert.

With Donald Trump back in the White House, this has meant that his wife, Melania Trump, has also stepped back into the limelight.

As First Lady, she has already attempted to make some law changes, as she made a rare appearance earlier this week when she called on lawmakers to crack down on ‘revenge porn’.

Speaking to Congress on Tuesday (March 4) Donald Trump brought attention to her work, which resulted in the First Lady getting a wave of applause across the room.

However, a body language expert has suggested that Melania may not have really enjoyed that moment.

Speaking to UNILAD on behalf of Prime Casino, Darren Stanton argued that Melania was actually frustrated about this mention and uncomfortable more than anything.

He added that her ‘smile’ was out of politeness rather than genuine joy at being mentioned by her husband as part of his address to Congress.

He said: “She doesn’t seem to like attention, she doesn’t like having focus brought on to her. They are not genuine smiles of elation. You can see from her eyes and the tension in her mouth that it was a very forced smile.

“She was not happy at all to have everyone looking at her. There were no crow’s feet and the top half of her face was not engaged in the smile at all.

“Trump likes to shift attention towards her but she would clearly rather remain out of the limelight. She was visibly very embarrassed and uncomfortable.”

Stanton also added that Trump continuously insists on putting Melania in the spotlight despite her apparent feelings towards this.

He also pointed out the clear differences in behavior when someone looks to be genuinely smiling and happy.

He added: “The key tells of a genuine smile are wide eyes, raised eyebrows and the mouth slightly open. Melania didn’t exhibit any of these. On the contrary her eyes actually seemed to tighten and her eyebrows pulled together and she pursed her lips.

“This suggests that beyond merely being embarrassed, she was actually quite angry. She did not want to be in the limelight and Trump always insists on putting her there. There were clear signs of discomfort and anger.”
