Clad in a skin-tight pink bodysuit, the 47-year-old singer's shapely legs are on full display as she struts about in her skyscraper heels.
After a few token arm movements, Mariah is picked up by a hunky male dancer, pulling a stiff smile as she lies in his arms.
He then lowers her down gingerly, with the Hero hitmaker looking a little uncomfortable as she pulls herself upright.
'Me doing the absolute bare minimum at work today #monday', one Twitter user joked, and a second shared, 'When you have to work on payday'.
'Omg I'd demand a refund', a furious fan wrote, while another posted, 'WHO THE HELL PAYS FOR THIS?! I WANNA KNOW!! LOL'.
Others found the video hilarious, enthusing, 'This is FANTASTIC' and a second, 'It was just for laughs since she knows she isnt a dancer. Her SINGING was on point though.'
MailOnline has contacted Mariah's representatives for comment.
