The mystery remains as to what substance Britney Spears was on last night when police showed up to the pop tart’s house. Here’s what we do know:
After a court-appointed child monitor called the police, a whole mess of flashing lights came to the house (which was already fairly well-lit). Britney was taken via ambulance to L.A.’s hospital-to-the-stars, Cedars-Sinai Medical Center. Paramedics attempted to strap down the pop tart’s legs in the ambulance.
