An unusual music video of Britney Spears lip-synching to Marilyn Manson's Eurythmics cover of 'Sweet Dreams (Are Made Of This)' was leaked to youtube yesterday. So what's the deal with the clip?

Apparently the video was recorded by Britney for use in her 2009 tour and shown during musical interludes. It's typical Britney, with her acting sexy in a gothic environment. So, although the explanation is less than exciting, the fact that it exists is pretty weird. Check it out for yourself below.
