Britney Spears’ career is full of highs and lows, and yesterday, some of her lowest moments were on display in a Los Angeles courtroom. Spears’ former manager, Sam Lutfi, is suing various members of Britney’s family, and claims Spears did drugs during her troubled times, People reports.

In opening statements, Lutfi’s attorney talks about the singer’s drug use during 2007 — the time when Lutfi was serving as her manager — saying, “Most of the things that went wrong related to that habit [of amphetamine use]… My client sometimes spent 24 hours a day to prevent Britney from using drugs.” He tried to portray Lutfi as a calming force during her troubled times. The Spears family disagrees: In 2009, a judge gave them a three-year restraining order against Lutfi.

In addition to seeking the 15% of Spears’ earning during the eight months he was her manager, Lutfi is also suing Spears’ parents for defamation and alleges Spears’ father, Jamie, punched him in the chest. He claims that accusations Britney’s mom wrote in her 2008 book, Through the Storm, — including that Lutfi “cut the phone lines in Britney’s home, disabled her cars and ground up medication and put it in her food in an attempt to cause a ‘sleep-induced coma’ at the urging of her doctors,” per People — aren’t true.

Britney herself is not expected to appear in court. An email to her rep was unreturned.
