When she's not worshiping Lucifer, Britney Spears is always pushing her brand. Today, that venture means unveiling her own iPhone and iPod Touch application.

The app is fittingly named "It's Britney!" and is currently available worldwide at the iTunes App Store for $1.99, which might be $1.99 more than it's worth to you.

With "It's Britney," fans get to the front of the line with all things Britney Spears - all the latest official news, exclusive messages, photos, lip-syncing videos, etc.

Additionally, the app features a "Shake Shake Shake" feature in which Britney says "It's Britney Bitch!" every time the user shakes their iPhone or iPod Touch.

We take it back, we'd pay $1.99 for that in a nanosecond. Although we'd prefer a Jon Gosselin app that says "I'm a douche" everytime you shake your phone.
