In the drawn out legal battle between Britney Spears’ mother Lynne versus the pop star and "X Factor" judge’s former manager Sam Lufti, matters are only getting uglier and more complex.

This week, the elder Spears received a court order against Lufti, who is Jewish, that bars him from accusing her of being an anti-Semite during the pair’s upcoming defamation battle, according to TMZ.

In 2009, Lufti first brought suit against Lynne Spears after she published her tell-all book Through the Storm: A Real Story of Fame and Fortune in a Tabloid World.” In it, she calls Lufti a “Svengali,” a word with roots in Christian mythology that describes an individual who practices mind control.

The word can also be construed as a reference to the “Wandering Jew” character in the same mythology, which Spears fears will trigger Lufti to call an expert witness to attest to the word’s potentially defamatory connotations.

Finding Spears argument to be valid and the calling of a witness on the matter irrelevant and prejudicial, a judge ruled to block Lufti from making any claims that Spears is anti-Semitic.

Still, Lufti is going after more than just one dubious reference. In total, he’s suing Spears for libel, defamation, battery, intentional infliction of emotional distress and breach of contract as a result of the book, which he says caused him “humiliation, mental anguish, and emotional and physical distress,” according to Fox News.

Also caught in the center of the legal battle is Britney, who a judge has ruled should not be forced to testify in the case. Lufti and his legal team feel differently however, as they claim her testimony would help bolster Lufti’s character claims that he was only trying to protect Britney.
