Britney Spears has teased the words to her forthcoming single.

The singer is due to unleash the comeback track 'Work Bitch' to radio on September 16 before it gets an iTunes release the next day.

She has previously uploaded images of herself from the song's video shoot to increase buzz around the track.

Spears has now shown fans a 'Work Bitch' lyric sheet - but its words are blurred.

However, its writers - William Adams (aka will.i.am), Spears, Otto Jettman, Sebastian Ingrosso, Anthony Preston and Ruth-Anne Cunningham - can be seen.

The former X Factor USA judge meanwhile is also due to appear on Good Morning America on September 17.
