Britney Spears' ex manager Sam Lutfi is suing the star as well as her family and has made shocking claims in court on Wednesday.
Lutfi first filed the lawsuit in 2009, less than one month after Spears' personal breakdown and forced hospitalization.
On Wednesday, Lutfi's testimony included claims about Spears and both her mother Lynne and father Jamie as he appeared in court over the lawsuit.
The ex manager described an incident where he and Jamie Spears clashed over who Britney's "true protector" was while in the singer's Beverly Hills home.
According to Lutfi, Spears "barged into the house, lunged at me with fists balled, and chased me around the kitchen island," reported People magazine.
"He was spitting, shouting and angry, saying I'd better leave Britney alone or he'd beat the hell out of me," Lutfi added during the testimony, according to People.
The following morning, Spears allegedly return to threaten Lutfi again.
"He came in, started yelling at me, accusing me that I was abusing his wife [Lynne Spears], cornered me in the kitchen, punched me in the [chest] and threatened to kill me," said the former manager.
Lutfi's lawsuit lists libel, defamation, battery, intentional infliction of emotional distress, and breach of contract. The case primarily focuses on the incident as well as the morning after.
Moreover, Lynne Spears in also named in the suit. According to Lutfi, her book, "Through the Storm: A Real Story of Fame and Family in a Tabloid World" published in 2008, implied that he had drugged Spears. As a result, Lutfi said Spears' fans targeted him and threats on his life left him "depressed, anxious, and suicidal."
"There were threats to kill me, people wishing I was dead," said the former manager. "People wishing harm to my family."
Additionally, he is suing the "Baby One More Time" singer for thousands of dollars of unpaid fees.
The singer nor her parents have publically addressed the lawsuit, but Lynne and Jamie Spears are expected to testify in court within the next few days, according to People magazine.
Last week, Lynne Spears reportedly won a court order against Lutfi, blocking him from describing her as an anti-Semite, according to TMZ.
Out of fear that Lutfi would accuse of her being racist, the pop star's mother blocked the former manager from bringing up any references to being anti-Semitic while in court for the trial.
