Britney Spears’s past nightmares came back to haunt Thursday as a trial pitting her former manager against the Spears family got under way in a Los Angeles courtroom.
Sam Lutfi, 38, is suing the pop star, 30 – who’s not expected to appear at the trial – for the 15 percent of her earnings that she allegedly promised him in the roughly eight months he served as her manager, starting in mid-2007.
He’s also suing her mother, Lynne Spears, for alleging in her 2008 book Through the Storm that he drugged Britney and cut her off from loved ones. And he’s suing Britney’s father Jamie for allegedly punching him in the chest in January 2008.
