In 2003, Beyoncé Knowles-Carter (then Beyoncé Knowles) released Crazy in Love.

It was her first solo album and her first time performing for millions of fans without Destiny’s Child. To cope with the new world of commanding the stage on her own, Beyoncé did what any talented performer would do: She called on her alter ego.

The world officially met Sasha Fierce on the album I Am… Sasha Fierce. But the alter ego was always part of Beyoncé, as she recalled in a 2004 Rolling Stone interview.

Who is Sasha Fierce? To put it simply, she’s Beyoncé’s more aggressive, sensual persona who really comes to life when the performer hits the stage.
