Britney Spears has revealed the cover art for her new single.

The pop princess is releasing the track 'Work Bitch' as her comeback track to radio on September 16 before it gets an iTunes release the next day.

The US star has now uploaded the single's artwork, which sees the singer wearing a snazzy blue show costume.

A Las Vegas logo can be seen near Spears, which hints at the singer's much-rumoured possible residency in the city.

Tweeting as she released the artwork, the singer said: "4 days people! Go call the Po-Lice! Go call the Governor!"

'Work Bitch' meanwhile is due to feature on Spears' forthcoming new album, which does not yet have a release date or title.
