Celebrity website TMZ has confirmed that Britney Spears has been released from Cedars-Sinai hospital, following an explosive morning pointing to a bipolar style attack.

Sources say the hospital released her without notifying any of the principles involved in the ongoing kiddie drama. So, you ask, how could she have been released so quickly, given that she had been declared a danger to herself and others?

We're told the "5150 hold" means that she can be held against her will for a max of 72 hours, but if the hospital determines she is no longer a danger, they can release her before that.

In other Britney news, Dr. Phil paid a visit to Brit this morning -- and she could return the favor next week by appearing on "The Dr. Phil Show."

The show is taping a special about Britney Spears on Monday, which will air on Wednesday.
