I don't understand those fangirls or fanboys..
That will be jealous and hating on the significant of their idol. Like the gf/bf/partner/spouse. People need to know that celebrities are human beings and that they can't be single forever just so that some certain people can fantasize about being with them! (And it will most likely never happen!)
Here is how not to be a fangirl/fanboy:
Example: When I liked the singer from Deathstars I would see some russian "fans" at VK, post nasty comments under a picture of him, holding around some girl (who might have been his sister for all we know). The "fans" (after I translated their comments) had written stuff like "What a fat cow! He could do so much better!!?" "This ugly b* needs to die! Seriously!!"
Here is how to be a good fangirl/fanboy:
Example: I just followed Schneider's wife on instagram and commented a picture of their lovely X-mas tree, telling her how lucky they all were for having each other, and wishing them a merry X-mas, because guess what?? I have seen their wedding photos and they look so f* adorable together! Seriously! They are so cute together with their two sons and I ship that couple so much! Yes of course I think Schneider is hot and I would be lying if I said I didn't fantasize about him, but I also happen to realize that Schneider like anyone else first of all is a HUMAN BEING and has found a gorgeous (my bi-metre/bifi wen't off the charts!) kind looking lady that he seems to adore and love. Why are some people upset about that??
To all the crazy fangirls/fanboys who obsess about their idol to the point that they deprive them/judge them of finding love: grow the f* up and get a life of your own! Your behaviour is not "cute" and I am sure it's not welcomed by your idol either!
Wake up honey, and smell the truth; You. are. insane. and. they. will. never. pick. you!
