Britney Spears is making her comeback, and not only with catchy, foot-tapping songs. The Britney Spears iPhone app, called ‘It’s Britney!,’ was launched by the pop sensation with the aim to make her life—and everything about her—super-accessible to fans.

The Britney Spears iPhone app will deliver fans with official news firsthand, exclusive tour images and messages from Spears herself, a 100+ photo gallery of Spears over the years, and a special ‘Shake Shake Shake’ function—when the user shakes his or her iPhone or iPod Touch, Spears’ voice says "It’s Britney Bitch!"
