BRITNEY SPEARS - JANUARY 31, 2008

TMZ has learned Britney's parents have won round one in the tug of war with Sam Lutfi. 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. At the same time, we're told Britney's mother, father and brother have been "working closely with the LAPD for weeks" to get her back in for psychiatric care. There is now a dogfight between Britney's family and Sam Lutfi over who will make medical decisions, however, that fight is now put on hold because the judge now makes the call. Once the psychiatric hold ends, something has to give.

TMZ has broken story after story in the middle of the night, detailing the second commitment of Britney Spears that occurred in the last few hours. For all of you who have just logged on, here's a summary:Last night, Britney's new psychiatrist went to her home and felt she was a danger to herself and others -- partly because of her reckless driving and partly because of her "downhill behavior." As a result, the shrink launched a plan (days in the making) to have Britney committed to UCLA Medical Center by calling the cops.Sources tell us the cops knew it was coming. In fact, the plan was for cops and paramedics to take Britney away the night before, but it was scrubbed. Last night, it all went down according to plan. Cops even used code to minimize craziness in transporting Britney to the hospital. Over the police radio, she was referred to as "The Package."

TMZ has learned there is a bitter fight underway as this story is published. It's taking place in the halls of UCLA Medical Center. As of right now, Jamie and Lynne Spears have been told they are not calling the shots in making medical decisions on behalf of Britney. Right now, it appears Sam Lutfi is in the driver's seat, but that could all change.Sources tell us after Britney's stay at Cedars earlier this month, she had her lawyers draft paperwork making it clear she did not want her parents involved in making medical decisions on her behalf. We're told her dad had gone ballistic back then, screaming and swearing at Lutfi -- even pushing him -- in front of Britney. As to what paperwork was signed, the cleanest thing would be if Britney signed a durable power of attorney, giving someone power to make medical decisions on her behalf in an emergency. We are told no such document was signed, but somehow Britney made it clear she wanted Lutfi to make those decisions.Right now, the doctors at UCLA are working with Lutfi and not the parents, but lawyers have been called and the tension in the air is thick. We're told Jamie was screaming at Sam in the hallway, accusing him of trying to control his daughter's mind.As for Britney, we're told she's not only calm, the doctors have just given her a "cigarette break!"

Unlike the last time she was committed, this time around Britney Spears was all about peace and silence as she waited for cops and paramedics to take her away.At her home earlier in the evening, we're told Sam Lutfi informed Brit he had been working with her psychiatrist and the cops, and she would be going back to the hospital. At that point, we're told, Lynne Spears became extremely upset and accused Lutfi of trying to control her daughter. Brit then told everyone to "shut up," saying "I'll do what I need to do."After that, Britney demanded complete silence. She sat on the floor and began passing notes to Lutfi, Adnan and others as they waited for the cops and emergency workers. Utterly different from the last time.

TMZ has learned the plan to get Britney into UCLA Medical Center had been hatched for days -- it was aborted last night, but executed just minutes ago.Back at her house, Britney's psychiatrist told her she was going to the hospital. Her response was, "Is something wrong?" She was not resistant. She made hot chocolate and waited before paramedics arrived and placed her on a gurney. We're told the psychiatrist felt her condition had deteriorated. Britney had not slept since Saturday -- a day and half longer than she stayed up in recent memory. The reason she's at UCLA is her new treating psychiatrist practices out of that medical center. We're told during her initial 72-hour stay she cannot be forced to take medication against her will. If, however, she refuses to take meds, the plan is for the the psych to go to court and have Britney held for an additional 14 days, during which time he can administer proper medications. And get this ironic twist -- Lynne Spears and Adnan drove to the Medical Center in the same car. A source tells us when Lynne found out Britney was being committed, she blamed it on Sam and was extremely agitated. When Brit heard that, she screamed to her mother, "Shut the hell up."
