The father of troubled singer Britney Spears has strengthened control over her affairs with an order to fire her business manager and a demand that he turn over her personal records, a court document showed on Friday.
The document, which was posted on celebrity news Web site TMZ.com, said that Howard Grossman was notified of a court order granting Jamie Spears the right to fire him as the singer’s business manager and require Grossman “turn over all documents, records, and assets relating to Britney Spears”.

The move follows charges by Spear’s mother Lynne in court documents made public earlier this week that the pop star’s self-style manager, Sam Lufti, had drugged her to take control of her home, life and finances. Her father was given temporary control over her affairs by a Los Angeles court.

Spears had left the UCLA Medical Center and one day later, Jamie Spears was back in court in a closed-door hearing to strengthen his conservatorship over her assets. Spears’ life has spun out of control since her divorce from ex-husband Kevin Federline in 2006. She has battled Federline for custody of their two young sons. Spears’ current Los Angeles attorneys in that case, the firm Trope and Trope, have filed court papers asking to be dropped from the case.
