Britney Spears former manager, Sam Lutfi, is reportedly planning to film a revealing documentary about the singer's highly-publicised breakdown. 
According to the Daily Star, Lutfi is said to be in talks with US TV network UPN, which broadcast Spears' 2005 reality series 'Britney and Kevin: Chaotic'.
Spears' parents, Jamie and Lynne, have publicly blamed Lutfi for the series of emotional breakdowns in 2007 that lead to the singer losing custody of her two sons to ex-husband Kevin Federline.
34-year-old Lutfi has filed a lawsuit against the Spears, accusing them of defamation and breach of contract, alleging their claims that he drugged the star were untrue and had caused him "humiliation" and "distress".
A source said: "Sam has realised that a TV show would get him a large chunk of money and he'd get extra money on the back of it in magazines and newspaper interviews."
