1 of 14Beyonce / Sasha Fierce
The general public wasn't introduced to Bey's more aggressive, sexual alter ego until the 2008 album I Am… Sasha Fierce. Beyonce conceived Sasha as a way to keep her powerful stage persona separate from who she really is, but in 2010 the diva said she was comfortable enough with herself that she didn't need Sasha. While Bey might not feel a need to rely on alter egos anymore, that doesn't mean she has ut them off completely. Her latest self-titled album introduced us to yet another side of the singer, Yonce, a more erotic and darker alter ego.
