There really are too many details floating around and they all mean basically the same thing. Brit is back in the hospital. Which one, how, why and by who is all depending on who you ask. We went with TMZ.

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."

Before the cops arrived, the shrink told her she was going back to the hospital and she offered no resistance. She said, "Is something wrong?" She made hot chocolate and waited. Her mom, Lynne, got extremely agitated, accusing Sam of engineering the impending commitment. We're told Brit told her to "shut the hell up." She demanded silence, sat on the floor and wrote notes to people who were there as they waited. When emergency personnel arrived, Brit went on the gurney without resistance.
