There have been times before when Britney was hospitalized but now she has been more than calm and cooperative.
At 1:30 AM she was admitted in UCLA Medical Center and those who accompanied were her pap boyfriend Adnan, Sam Lufti , her parents, Alli Sims. When she had first arrived at the hospital, her father Jamie was seen crying.

According to sources at TMZ, an L.A. County Superior Court judge has signed a "5150," meaning Britney is on a three-day psychiatric hold at the UCLA Medical Center. The same thing happened during her January 3rd meltdown, but Britney was released early because she wasn't a threat to herself or others.
UPDATE: Sam Lutfi can hit the curb because Britney's parents are calling the shots for now. The docs at UCLA are "fully cooperating" with Brit's parents for Britney's recovery. Now, the judge has to sign an order to determine who is in charge. Let's hope he picks her parents because Sam hasn't done well till now.
