Sam Lutfi, former friend of manager of Britney Spears, has filed a lawsuit against the singer and her parents for libel and defamation.

He is also looking to collect on some unpaid management fees he insists he is owed.

The claim was filed in Los Angeles Superior Court on Tuesday, just three days after a judge granted Jamie Spears, who is conservator of the star’s estate, a restraining order against Sam and Britney’s paparazzo ex, Adnan Ghalib.

Sam claims that the Spears family “began a campaign of slander, libel and defamation aimed at discrediting, destroying and physically and emotionally intimidating Lutfi in order to drive him out of Britney’s life.”

The suit cites Lynne Spears’ 2008 book, Through the Storm, which Sam says is filled with “false statements” about him.
