Beyonce / Sasha Fierce
Beyonce invented her alter ego Sasha Fierce to separate her wild onstage persona from her more reserved everyday self. "I've created an alter ego: things I do when performing I would never do normally. I reveal things about myself that I wouldn’t do in an interview. I have out-of-body experiences [on stage]. If I cut my leg, if I fall, I don’t even feel it. I’m so fearless, I'm not aware of my face or my body,” she told Marie Claire. —Jeff Royer
