I think that everyone who has an alter ego and publicly points it out, is just trying to make himself / herself more interesting and get promo. If I had two personalities, I would try to hide them so my relatives wouldn't send me to an asylum...
However, Beyoncé seems that she left her alter egos behind two eras away (I might be wrong, I'm not that familiar with her music, music, whatever that includes alter egos) so I guess she's grown up and she decided to focus on her music, not on some
cimcumstances. And that's only good.
