STANDING by as your husband becomes President of the United States isn't the sort of thing most women prepare for when they get married.

That could be why Melania Trump was spotted switching between a beaming smile and a serious frown as she watched her husband Donald Trump's inguration last week.

Of course people were quick to pick up on the former model's apparent change of mood after her husband turned to look at her, with many posting comments about it online.

Dressed in a baby blue Ralph Lauren outfit which was reminiscent of Jackie Kennedy, Melania seemed glum as she stared at the floor behind her husband.

On top of that came the embarrassing footage of Trump striding up the stairs to the White House to meet outgoing President Barack Obama and his wife Michelle - with Melania trailing behind.

The new First Lady did get a welcome from Barack and Michelle - after an awkward gift exchange - but it'd led some internet users to joke about just what's going through Melania's mind.

The hash tag 'free Melania' has been trending, with many wags joking the 46-year-old needs more support in her new role.

One Twitter user even mocked up a joke version of the giant Tiffany box the new First Lady offered Michelle on inauguration day.

Instead of containing a sizeable present from the famed jewellery shop, he cheekily suggested it boasted a single post-it note emblazoned with the world 'help'.

Well you have to admit, Melania's experienced a pretty sizeable life change since her hubby clinched the election in November.

Other Twitter users joked about the flutter of blinking Melania did as her spouse was sworn in, while some tied the whole hashtag into other world events - notably the Oscars.

And of course there were some comments on the pretty awkward dance the couple shared at the inauguration ball last week.

Of course not everyone agrees with the joke.

Many have flocked to Twitter to ask others to stop speculating about the First Lady, insisting she is doing her best to get used to her new role and should be given time to adapt.

He may have only been president for a couple of days, but Trump has already made his mark.

There have been astonishing claims that one of his inauguration bodyguards wore fake arms so his finger was always poised on the trigger of his gun as he protected Trump, while the president is gearing up for a meeting with Theresa May later this week.
