Another user, @RaveHawk2012, appeared to genuinely appeal for support.
"Hi Kim, not sure if this message will find you but, if it does, do you think you could help support Armenia's football captain? He's had to pull out of a final because he's Armenian. Is there a way you could help Henrikh? Thanks," the user tweeted.
Kardashian's ancestry to Armenia comes through her father's side and she visited the country with her family in April 2015.
In an interview with the BBC, Arsenal's club captain Laurent Koscielny addressed Mkhitaryan's situation, and said: "When one country has a political problem with another then UEFA shouldn't give the final to that country.
"We want Mkhi with us because he is an important player for Arsenal. But we know about the problems and if he thinks he can't be safe it's better for him to stay here.
"This final is very far for the fans of both teams and it's difficult and very expensive to travel to Baku. We will play the game but it's not the final we dreamed of."
