A Los Angeles court commissioner has extended the conservatorship of Britney Spears.

Commissioner Reva Goetz told Spears' father James and a battery of lawyers Thursday that the pop star will remain under conservatorship until a hearing now scheduled for March 10. The troubled singer's father and an attorney were first named her conservators at the beginning of February.

An attorney for Spears' father also told the court that investigators have spent over 200 hours trying find the Britney Spears' sometime manager and friend Sam Lutfi to serve him with court papers.

The commissioner agreed to reissue a temporary restraining order against Lutfi if he is not served soon.
