The footage was played during a costume change on the star's 'Circus' world tour, which travelled throughout 2009.
The visual sees Spears at a gothic-styled masquerade ball, while Manson's cover of Eurythmics' classic 'Sweet Dreams' plays over the top.
Spears can be spotted singing along to the track in the video as she sensually walks around a room of writhing bodies.
It is the first time the footage has appeared online after it leaked earlier this week.
Spears is currently touring Europe with her 'Femme Fatale' world tour, while a DVD of the star's show will be released on November 28.
The 29-year-old recently debuted the music video for her new single 'Criminal', which is available to download now.
