Britney Spears' father will continue to look after her financial and personal affairs until a doctor has made a psychiatric report, a court has ruled.
Spears' ex-husband has been awarded custody of their children
Court commissioner Reva Goetz has appointed a doctor to judge if Spears - admitted to a Los Angeles hospital last week - is capable of making decisions.
James Spears will keep control of his daughter's assets until the report is considered at a 14 February hearing.
They were placed under her father's "conservatorship" at the weekend.
US courts take such measures when it is deemed someone is incapable of caring for him or herself or cannot handle their own affairs.
As conservator, Spears' father has powers over her liquid assets and can also bar people from contacting her.
Such a restraining order - sought by James Spears - was granted at the weekend against Spears' manager Sam Lutfi.
The order - now extended by the court - bans Lutfi from any contact with the 26-year-old singer, including phone calls and text messages.
The court rejected a bid by lawyer Adam Streisand - acting for Britney Spears - to take control of her assets instead of her father.
Spears' spell in the UCLA Medical Center is her second time in hospital in less than a month.
She was admitted to Cedar-Sinai Medical Center in January after refusing to surrender custody of her two sons in a police stand-off.
Sole custody of her two young children was subsequently awarded to ex-husband Kevin Federline.
