Jamie Spears has been the go ahead by LA courts to get rid of people he feels that are a threat to his daughter Britney and the first casualty is the "Toxic" star's business manager. A Los Angeles court granted Jamie Spears' request to fire Britney's business manager Howard Grossman during a hearing on Thursday, in which he requested additional powers over his troubled daughters affairs. Poppa Spears took control of Britney's money and assets after his daughter was committed into a psychiatric ward at the UCLA Medical Center in Los Angeles last week. Britney's parents reportedly dislike Grossman because of his close-relationship with the star's self-proclaimed manager Sam Lutfi, who they claim drugged their daughter. Documents released last night show Grossman was served with the legal documents on Thursday afternoon. In the papers Los Angeles Superior Court commissioner Reva Goetz ordered Howard Grossman to 'turn over all documents, records and assets relating to Britney Spears.' The order came after Goetz held an emergency closed-door hearing brought by Jamie Spears and co-conservator, attorney Andrew Wallett. Finally pest control has been called in!
