A Superior Court commissioner gave Britney Spears' father the power to fire the singer's business manager, according to documents released Friday. Commissioner Reva Goetz also ordered Howard Grossman to turn over "all documents, records and assets relating to Britney Spears" to James Spears, who is the court-appointed conservator of his daughter and her estate. The order came the day after Goetz held an emergency closed-door hearing on a motion brought by the singer's father and her lawyer Andrew Wallet, who is part of the conservatorship.

Spears' parents said they feared their daughter's life was at risk after she was released from a hospital psychiatric ward on Wednesday.

Spears' affairs were placed under a temporary conservatorship after she was taken to UCLA Medical Center on Jan. 31 under heavy police escort. Conservatorship are granted for people deemed unable to care for themselves or their affairs.

The conservatorship lasts until Feb. 14.

Spears was discharged from the hospital over the recommendation of her psychiatrist and against the wishes of her parents. Her parents said they were extremely disappointed she was released and they said they were deeply concerned about her "safety and vulnerability and we believe her life is presently at risk."

Spears slipped out of the hospital unnoticed by the pack of paparazzi that follow her every move in public, but they gave chase later in the day when she left her home behind the wheel of her Mercedes-Benz and eventually showed up at the Beverly Hills Hotel.
