Britney Spears Taken to Hospital After Custody Standoff

It was a chaotic night at the Spears household, as police were called to Britney's home in a custody dispute that "lasted nearly three hours before an intoxicated Spears reportedly turned over her children to ex-husband Kevin Federline."

Officer Jason Lee, a police spokesman, told City News Service: "Officers were called to the home around 8 p.m. on Thursday, and the 26-year-old singer turned over the children around 10:50 p.m."

Lee also said that "Spears was under the influence of an unknown substance, and no injuries were reported." He added that the incident involved a family dispute that police worked to resolve "peacefully by court order".

After handing over her sons, Jayden James and Sean Preston, Britney was then placed on a gurney and taken to Cedars Sinai Medical Center for what police are calling a "medical hold" - which is basically a mental evaluation period.

At that time, Jayden was also taken to the hospital for unknown reasons, while Sean Preston was whisked off in a black VW.

Update: Britney's father, Jamie Spears, showed up at the hospital to see his daughter, and Jayden was spotted in a car with an unidentified woman outside the hospital, being taken to Federline's custody.

Update: Inital reports from police claimed that Britney was intoxicated, but hospital tests tell otherwise. “Her blood test just came back, and, thank God, it was clean. There are no traces of drugs or alcohol of any kind,” a source told Life & Style.
