Britney SpearsBritney SpearsBritney Spears' father is now in control of her affairs.

The move follows her admission to a hospital psychiatric unit earlier this week.

A Los Angeles court has awarded Jamie Spears and attorney Andrew Wallete temporary command of Brit's multi-million dollar estate.

The order, referred to as a conservatorship, is passed in circumstances where a court rules that an individual is incapable of caring for themselves or unable to properly manage their own affairs.

In a separate ruling, TMZ reports that the judge at Britney's hearing also issued a restraining order against Brit's pal Sam Lutfi, after concluding that he had been harassing the star.

Brit's father also has permission to change the locks on her property, and remove anyone who is there.

Before the hearing took place, Sam was quoted by People magazine as criticising Brit's family, saying:

"Britney is fully capable of handling her own finances. Her doctors are capable of handling her health care.

"You'd think in a time like this, the family would be at the hospital taking care of their daughter, rather than fighting for her money. How sad."

Brit was rushed to UCLA medical centre in the early hours of Thursday morning, after reportedly being unable to sleep for five days.

Prior to the court ruling, sources from the centre had told TMZ that Brit has been classified as "GD" - Gravely Disabled, meaning a patient is deemed unable to take care of their own basic needs such as getting food or clothing.
