What was Beyoncé’s 2008 studio album titled, using her two contrasting personas?

Beyoncé’s 2008 studio album using her two contrasting personas was titled I Am... Sasha Fierce.

The album was structured as a double album. The I Am... disc focused more heavily on ballads and personal material, while the Sasha Fierce disc emphasized a bolder, more performance-oriented style. Beyoncé described Sasha Fierce as an alter ego associated with her stage confidence.

The release produced several major singles, including “If I Were a Boy,” “Single Ladies (Put a Ring on It),” “Halo,” and “Diva.” “Single Ladies” became especially famous for its choreography and black-and-white music video. The album was released after B’Day and before 4.

The title is often shortened in conversation, but its official styling includes the ellipsis and the name Sasha Fierce. It is distinct from Beyoncé’s later use of alter-ego concepts in performances and visual projects.
