Britney Spears Scandal Video Breakdown

Shooting on Britney Spears' new music video was stopped after the singer reportedly "sobbed hysterically" during a pole dance routine.

The troubled star, who was filming the promo for new single 'Give Me More', apparently looked "dead-eyed" and "disorientated" and became paranoid during her raunchy pole dance last Wednesday (25.07.07).

A source said: "Britney was rude, and she chain-smoked and drank an enormous amount of Red Bull throughout the shoot.

"She had a problem with the extras watching her pole dance, suddenly she was in floods of tears. It was sad to witness."
