Britney's latest impersonations of a crazy person:
"During the shoot, the 25-year-old mother-of-two was said to be "completely out of it", and the resulting pictures are "so bad" that publishing them could "kill her career".
At one stage Britney's eyes allegedly rolled back in her head and she was said to have looked "half dead".
Her mood was described as extremely erratic, with one source revealing she took frequent bathroom breaks and each time she returned her mood had changed.
She was also allegedly severely paranoid during the entire interview, and at one point she believed the ceiling was about to cave in.
During the shoot, Britney ordered fried chicken, and when she had finished eating it she reportedly wiped her hands on a Gucci dress worth several thousand dollars, staining it with grease."
