The singer tapes a concert for ABC's "Good Morning America" on Sunday.

Britney Spears was in San Francisco on Sunday to kick off her new album, Femme Fatale.

Fans lined up at midnight to watch her performance at Bill Graham Civic Auditorium.

Spears has called Femme Fatale "the best album I've ever made."

Her seventh studio album, due in stores this month, "speaks for itself," she tells the March issue of V magazine.

"I worked really hard on it and spent almost two years recording it," she adds. "There's nothing to say. I'll let the music speak for me."

Viewers who missed the show can watch Tuesday on ABC's Good Morning America or check out the clip of her performing her single "Till the World Ends" below, which was uploaded onto YouTube by a user named TeamAims.
