The LAPD was called to the Beverly Hills home of Britney Spears after her parents discovered valuable possessions belonging to her were missing.

Spears' father Jamie and mother Lynne were "shocked" to find that that valuable items "had been stolen" after they returned to the house following yesterday's emergency hearing where Jamie won legal control over his daughter.

They then called police and filed a report.

Britney Spears' parents believe that the items were stolen after their daughter was taken to the UCLA Medical Center early Thursday morning.

Britney Spears will stay in the UCLA psych ward at least two weeks.

Los Angeles Police officer Alex Martinez confirmed that police responded to a call at Spears' house, but did not know what had transpired.

"The report is being processed through our system," he said. "We do not have access to it at this time."

Police say Britney's parents filed an official report, claiming that the alleged theft occurred sometime between the time Britney was admitted to the UCLA psych ward and the time the conservatorship papers were signed.

Sam Lutfi has not been named as a suspect, however, he had access to the house, and Britney's father strongly believes Sam is up to no good.

Meanwhile, TMZ reports that sometime tonight, papers will be signed at UCLA extending Britney Spears' stay at the psych ward - by 14 days.

It's an internal process - done without a court order. It will indeed happen, and that's not surprising given her mental health.

Britney Spears has been diagnosed with severe bipolar disorder. The ward Britney is in right now is considered one of the best in the nation.
