A funny video of Melania Trump being rather obviously upstaged by a K-pop star has taken social media by storm, racking up thousands of views, and prompting hundreds of Twitter responses from amused viewers.

The clip, which was taken on Tuesday in South Korea, at an event to promote the 2018 Winter Olympics in PyeongChang, sees the 47-year-old First Lady posing for pictures with a group of school girls, happily smiling at them as they begin screaming in excitement.

However her happy look quickly turns to one of confusion - and perhaps even disappointment - as she realizes that the youngsters' enthusiastic display wasn't anything to do with her, but was instead prompted by the presence of pop star Choi Min-ho, a member of the incredibly popular boy band Shinee.

Awkward! A video showing Melania Trump being upstaged by a K-pop star Choi Min-ho during an event in South Korea has gone viral on social media

Confusion: The 47-year-old seemed rather put out when she realized who the girls were actually screaming for

At the start of the now-viral video, Melania is seen chatting with one young girl, posing alongside her and happily smiling in her direction, before one of her friends glances behind the First Lady and starts screaming excitedly and clapping her hands.

Apparently under the impression that this reaction was aimed at her, Melania flashes a wide smile at the overwhelmed young woman, who fails to so much as glance in her direction, instead directing her full attention to the pop sensation standing behind her.

She quickly alerts her friend to Minho's presence, whacking her on the arm and urging her to turn around, before both girls begin screaming with joy.

The young do and several of their male companions, who are all wearing smart school uniforms and white PyeongChang 2018 caps, then proceed to rush past Melania and crowd around the 25-year-old chart-topper, who looks completely unfazed by all the attention.

Melania quickly regains her composure after spotting the pop sensation, and gamely pats him on the arm, while laughing at the situation.

Minho, meanwhile, seemed delighted about the entire experience, and is seen in the video making a funny face at Melania, grinning at her with wide eyes when she first turns and realizes he is standing alongside her.

Unsurprisingly, the clip from the event, where Melania gave a speech on the importance of giving girls equal access to sports, quickly went viral on Twitter, receiving tens of thousands of views - and plenty of funny responses.

Whoops: At first, Melania began smiling at the two girls in front of her, apparently under the impression that their excitement was aimed at her - rather than Minho, who was behind her

Surprise! 25-year-old Minho seemed to find the situation hilarious, and grinned in delight at Melania as she turned around to look at him

Realization: The mother-of-one seemed very confused at first, but quickly smiled at the pop star when she worked out who he was

Moving on: After initially looking incredibly confused at the girls' reaction, Melania appeared to regain her composure and happily smiled while posing for more pictures with Choi Min-ho

'I mean if Minho was stood behind me I think I'd react the same,' one person joked on the social media site.

Another person noted that they had 'never seen Melania smile this much before', while dozens of other users tweeted hilarious gifs to spoof the girls' reaction to the popstar's presence.

However many South Korean Twitter users were quick to praise the First Lady's interaction with the girls and the K-pop star, especially her long-lasting smile.

'She smiles a lot, speaks well and is so kind to the teenagers,' said one person.

'I saw her smiling like that for the first time,' another said.

The event which was aimed at promoting an initiative dubbed Girls Play 2! took place at the U.S. ambassador's residence in Seoul, while President Donald Trump attended a summit with South Korean President Moon Jae-in during his two-day visit to South Korea.

After overcoming her slightly awkward photo call, Melania went on to make a passionate speech during the event, calling for boys and girls to be given equal access to sports.

'Sport teaches children about teamwork, dedication, discipline, and how to succeed under pressure.

'When we assure girls and boys have equal access to sports we are ensuring they have an equal chance to gain these valuable skills

'Girls Play 2 reminds people that girls love to play sport just as much as boys do. Girls wants to play basketball and hockey, and snowboard and ski.'

The President and First Lady have since moved on to Beijing, and from there they will go on to visit Vietnam and the Philippines.
