HAPPY FEMME FATALE DAY!

Britney took to the stage at the Bill Graham Civic Auditorium in San Francisco on Sunday for Good Morning America to perform three cuts from her brand new seventh studio album, Femme Fatale: “Hold It Against Me,” “Big Fat Bass” and “Till The World Ends.”

Aside from the performances, Britney also announced that she’ll be kicking off a US tour in June with Enrique Iglesias–for the first round of tour dates, check Billboard.biz.

Britney will also performing again today at midnight on Jimmy Kimmel Live!.

To celebrate the release of Femme Fatale, please enjoy this brand new remix of “Till The World Ends,” free for download courtesy of Doctor Rosen Rosen!

In keeping with the good doctor’s penchant for dance floor haunts, the re-rub finds Britney sounding eerier than ever above echoing synthesizers, disjointed strings and a chorus that takes the song’s drunk chanting and turns it into a choir of hellfire and damnation. It’s a bit more Halloween than it is A Night At The Roxbury–but hey, we love it just the same!

Femme Fatale was released today, March 29. (iTunes)
