Britney is now on a psychiatric hold at UCLA Medical Center.

According to the Los Angeles Times, it was a phone call to authorities from BRITNEY SPEARS' psychiatrist which led to her hospitalization in the psychiatric unit of UCLA Medical Center early this morning. The Times reports that Britney's admittance was actually a carefully planned event that had been orchestrated over time.

A motorcade of more than a dozen law enforcement vehicles, including police helicopters, followed an ambulanced Spears as she was admitted to the hospital shortly after one in the morning.

She has been placed on a 5150, which is a 72-hour hold, as she is evaluated and treated.
