Britney Spears was rushed to the Cedar hospital late last night. K-Fed also showed up to show his support… What’s wrong with her? Who knows, but the police reports states she was under the influence of an unknown substance. Check out the video below…

UPDATE: It seems that K-Fed’s Bodyguard went to pick-up the kids and Brit locked herself in her bathroom with the two kids (acting erratic). The Bodyguard called the police to enforce the court order to turn over the kids. When the police arrived Britney let the kids out of the bathroom. The cops on the scene found Britney to be under the influence of some substance.

They forced her to go to the hospital for psychiatric evaluation (police code 5150 : possibly endangering herself or others). ALSO, her youngest Jayden James was also taken to the hospital in a separate ambulance , Condition unknown.
