How do you differentiate beyonce and sasha fierce?

Hi, nafmdt. I don't think that it is an indication of Beyonce having a split personality. It is just her wild side that is coming out and letting loose. I am sure that we all have a different side to us. One that we keep hidden and the other one that we show to the world. It is just another part of our personalities.

I don't think it's necessarily a split personality I think Sasha fierce is a personality that comes out when she is performing, she does seem sweet and calm, and innocent in her regular life but on stage you really do see a fierceness that comes out in her performances. It's just like Michael Jackson, when he performed its a total different person that that child-like personality he displays when not performing, maybe it's an alto ego or split personality but you got to admit, it's really good
