What is the name of Beyoncé’s 2008 double album featuring “Single Ladies”?

Beyoncé’s 2008 double album featuring “Single Ladies (Put a Ring on It)” is I Am... Sasha Fierce.

Released on November 12, 2008, the project was structured as two discs. I Am contained more introspective ballads, while Sasha Fierce emphasized a more confident and performance-oriented persona. The title referred to the stage alter ego Beyoncé had developed earlier in her career.

“Single Ladies (Put a Ring on It)” became one of the album’s defining songs and was accompanied by a widely imitated black-and-white music video featuring choreographer JaQuel Knight. Other major tracks from the project included “If I Were a Boy,” “Halo,” and “Diva.”

The album title is sometimes shortened incorrectly to “Sasha Fierce.” Its full official title includes both parts, reflecting the contrast between the album’s two musical moods.
