The fandom of male and female artists is just strange, especially those with a high female following. The fans of male artists generally regard them as their "boyfriend." It's only natural for her to spend money on her idol; she's got stronger fighting spirit and purchasing power. That is, as long as the artist's persona doesn't crumble, and he doesn't get a girlfriend.
As for the fans of female artists, especially female fans, they generally have a maternal mindset. When a female artist gets into a relationship, on one hand, they resent the man for digging into their precious gem, and on the other, they fear that he might hurt their beloved artist and cause her pain. However, if she manages to find a man who is both outstanding and dotes on his wife, most people would still send their blessings.
