Adelya and Alina Fakhteeva are Russian twins who share posts for their 176,000 followers including photos with designer brands, posing seductively together and lounging on yachts and in private planes.

But one of their most recent posts has gotten attention for all the wrong reasons, as it shows Adelya and Alina feeding a homeless man sushi in what has been branded a shameless publicity stunt.

The clearly-planned video shows the pair in matching designer outfits spotting the man before commenting: "Poor thing, he probably hasn't eaten for a long time."

They call a restaurant and a deliveryman soon arrives with a tray of sushi which the twins feed to him using chopsticks, before leaving him to feed himself.

"Everyone knows that there are good people who can help," the homeless man says before the clip ends.

Though the man in the video - identified as Yuri Zasorin - is genuinely homeless and has been for 28-years in the Russian city of Kazan, that's just about the only 'real' part of the video according to viewers.

Many were unimpressed by the girls' video and the caption they paired it with, which claimed stray cats are "nicer" than homeless people.

"Every day we see people in the street who need help," the duo captioned their video. "After all, are we within our power to pay attention to them? Do not pass by ... Yes, homeless cats may be nicer, but people also need our help, support. And we care!"

The last line is a reference to a competition called 'We Care' organised by a local group, which offers prizes like an iPhone XR, a PlayStation 4, an Apple Watch Series 4 for random acts of kindness.

Fans and critics are unimpressed with the twins' entry, both for its content and the fact that the rich 24-year-olds likely don't need any of the prizes up for grabs.

"These twins are so divorced from real life that they do not even understand how the poor can be helped," wrote one critic.

"So much hypocrisy in these forty-two seconds," another added.

Adelya and Alina later disabled the comments section on their video, but it didn't stop the criticism, with some Instagram users moving to the twins' other posts to slam their "disgusting" behaviour in the video.
