More from TMZ:

We’re told the doctors at UCLA are now “fully cooperating” with the parents in the treatment of Britney Spears, however, the war probably is not over until a judge signs an order as to who has control.

By the way, the men in white coats are giving props to LAPD’s “SMART Unit” which specializes in mental health cases for coordinating the events that went down last night and early this morning.

UPDATE: Sam Lutfi left the hospital before 4:00 AM. Papa Jamie just left.

Law enforcement sources tell TMZ an L.A. County Superior Court judge has just signed a “5150,” meaning Britney Spears is on a three-day psychiatric hold at the UCLA Medical Center.

We’re told there is a “good possibility” that it will be extended to 14 days. We’ve also learned there have been several parallel attempts to get Britney on a 5150. Her lawyers, Anne Kiley and Tara Scott, secured a new psychiatrist late last week — he’s the one who triggered the 5150 last night.

Once the psychiatric hold ends, something has to give.

These pictures were taken just hours before Britney was committed last night.  She was pictured having lunch with Adnan at Jerry’s Deli for lunch in LA.
