Described as being "sexy, seductive and provocative" when performing on stage, Beyonce has said that she originally created the alter ego "Sasha Fierce" to keep that stage persona separate from who she really is. She described Sasha as being "too aggressive, too strong, too sassy [and] too sexy", stating, "I'm not like her in real life at all." Sasha was conceived during the making of "Crazy in Love", and Beyonce introduced her with the release of her 2008 album I Am... Sasha Fierce.
