Dear User,
Thank you for your question.
One reason might be due to fanboying or fangirling, which is overly paying attention to celebrities. Some fans are so obsessed with celebrities that they don’t want to see them being in love. Some fans are deluded and think that their favorite celebrity needs only love them. When they are in love with someone else, fans could feel betrayed by them.
Another reason might be due to jealousy. The gap some fans might feel in money and appearance might make them jealous of their idols, and how their life is so much better than them, which generally gives them feeling of inadequacy.
Finally, some fans don’t think celebrities are human. Some fans think celebrities are famous people that have no interests and personal life and therefore are shocked and disgusted to find out that they have interests and lovers.
I hope this was helpful.
