A California appeals court has rejected a bid by Britney Spears' mother to have a defamation claim by the singer's former manager thrown out.
Lutfi sued Spears and her mother, Lynne Spears, for libel and defamation in February 2009. The case cited numerous passages from Lynne Spears' book, "Through the Storm," in which she accused Lutfi of drugging and controlling her daughter.
The allegations were also contained in court filings that led a judge to establish a conservatorship involving the Grammy-winning singer.
Lynne Spears' attorney, Michael Adler, declined comment.
