Britney Spears Legally Insane?

It looks like this has reached the boiling point with Britney's antics.

It is not humanly possible to write a soap opera as dramatic as the life Britney Spears actually lives.

Tonight at Spears' home, while allegedly on some sort of drugs, Britney refused to hand over her children to Kevin's bodyguard at the court appointed time. The standoff lasted over four hours, and police, as well as Kevin himself came to confront the popstar.

Tmz is reporting that an ambulance actually took Britney from her home in a gurney, and that after over a year of totally insane behavior, medical professionals will finally have their say in the matter.

We're told Britney is being taken to a local hospital on a "medical hold" -- essentially a mental evaluation. Cops found her earlier this evening at her home under the influence of an "unknown substance."
