LOS ANGELES (Reuters) - 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.

Late last week the 26 year-old, who rose to stardom as a Disney child star and became a teenage pop singing sensation, was admitted to a Los Angeles hospital and placed under psychiatric evaluation.

Her father was given temporary control over her affairs by a Los Angeles court.

By Wednesday, 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 spent time in rehab, been photographed in public wearing no underwear and exhibited bizarre behavior such as wearing pink wings and talking in a British accent despite being from Louisiana.

She has battled Federline for custody of their two young sons, and in another public disclosure on Friday, Spears’ current Los Angeles attorneys in that case, the firm Trope and Trope, have filed court papers asking to be dropped from the case, according to TMZ.com.

Britney Spears Denies Pregnancy Rumors As Concerns For Her Survival Intensify

Inappropriate photographs of the singer surface; news organizations confirm they are preparing obituaries.

Britney Spears is not pregnant, as photos that just surfaced online demonstrate.

The singer had been photographed at a Rite Aid in Los Angeles on Monday browsing home-pregnancy tests with her paparazzo boyfriend, Adnan Ghalib. She sparked speculation about her state of fertility with the photo stunt, a sort of is-she-or-isn’t-she game, as her associate Sam Lufti told “Access Hollywood.” “It’s all bullsh–,” he said. “They’re just toying with the paparazzi.”

Spears dispelled the rumors herself when asked if she had tested positive, telling photographers and videographers, “I never had a pregnancy test. It was for my friend.” (We assume she meant Ghalib, whose photo agency, FinalPixx, had the exclusive on the shopping shot.) Whether intentional or not, the singer later provided further evidence that would seem to confirm that statement, via a series of highly inappropriate photos taken by paparazzi as she left a Kitson clothing store late Wednesday night.
