Britney Spears youngest son Jayden James was also taken to a hospital last night.  No word on why J.J. was sent by ambulance to the hospital as well.

Two ambulances left Britney’s house, both headed for Cedars-Sinai Medical Center — one transporting Britney, the other had two-year-old Jayden James in it!

Cops, firemen, and paramedics were sent to Spears home for a nearly three hour standoff before Britney agreed to give her children back to her ex-husband Kevin Federline.

Britney was taken by stretcher to Cedars Sinai for a mental evaluation.
