BSpearsKIDS100812_01_230.jpgOpening statements for Sam Lufti's breach of contract/defamation suit against Britney Spears and her conservators began yesterday and the singer's former manager had some explosive information to share.

Lufti's lawyer, Joseph Schleimer, claimed that not only did Britney's amphetamines use was the cause of everything that went wrong with the pop star but also that he never gave her the drug Adderall and even tried to help save her.

Continuing with their opening statements, Schleimer claimed that in an attempt to clean Britney's house of drugs, Lufti discovered a bag of crystal meth -- citing that as one of the chief reasons she infamously shaved her head during her 2007 meltdown. X17 was there when the incident took place, having exclusively reported on their relationship before Lufti became a household name.

In his suit, Lufti states that Britney's conservators violated the terms of his verbal agreement with Spears for him to act as her manager and that he's due a cut of her $15 million X Factor contract. In addition, he claims Britney's mom Lynne Spears libeled and defamed him in her book Through the Storm: A Real Story of Fame and Family in a Tabloid World.

Lufti and his legal team hope to bring Britney on the stand to tell her side of allegations that her mother made in her book, stating he disabled Britney's car batteries and fed her drugs in an attempt to keep her under his control. The trial is expected to go underway today.
