Britney Spears is reportedly furious over a leaked and unfinished version of “Womanizer,” her first single that hit the net recently. “Record company bosses have been frantically trying to pull the material from the internet. It’s not good for Britney’s comeback if people aren’t listening to the polished version” says a source close to the singer’s management. Spears’ forthcoming album “Circus” was moved up to a December release due to the buzz surrounding her MTV Video Music Awards appearance. Spears picked up three awards that night including ‘Video of the Year’ for “Piece of Me.” In related news, friends of the singer are concerned about the new album and Britney’s schedule. “Britney has been putting in every hour under the sun to get herself ready in time for the release of ‘Circus’. It’s too much too soon. This will set her back mentally and physically unless she takes the pressure off” a friend told Britain’s Daily Star. Spears has shed one thing though. The singer has placed her $7.9 million Studio City, California home on the market. The six-bedroom, six bathroom home has been described as an exquisite gated Italian Renaissance-inspired villa with three garages and a grand entrance foyer. The “Womanizer” singer hopes to have more privacy and wide open space to raise her boys. “Womanizer” is slated for release September 29th (moved from September 22nd).
