Britney Spears was taken out of her home via ambulance last night after reportedly refusing to hand her children over to Kevin Federline's bodyguard.
After more than an hour with the kids locked inside the house, police were called to the scene and found Britney to be "under the influence of an unknown substance." Paparazzi and local news crew cameras swarmed the gates of Spears' gated community, and snapped photos of a dazed Britney in the back of an ambulance.
Britney was then taken to Cedars-Sinai Medical Center and is being placed on a "medical hold."
Kevin Federline showed up to support his ex-wife as did Jamie Spears, Britney's father, and Sam Lufti, her constant companion.
