What started out as a typically self-destructive day for Britney Spears escalated into a heated standoff at her home involving police, EMTs and media helicopters hovering over the scene. Hours later, Spears - strapped to a gurney but smiling - was taken to L.A.'s Cedars-Sinai Medical Center ( watch ambulance video here, courtesy CelebTV.com).

Earlier on Thursday, Spears showed up for the court-ordered deposition she had shrugged off multiple times before - albeit two hours late. Thus, she was only able to give ex-husband Kevin Federline's lawyers some 12 minutes of her time.

Then last night, starting at 8 pm, K-Fed's bodyguards arrived at Brit's house to claim the kids for Dad's scheduled visitation. Spears, though, refused to turn them over, igniting a standoff that lasted until 10:50 and necessitated the arrival of six police cars - court-dispatched to settle the sitch "peacefully" - an ambulance and a fire truck. "[The court-appointed monitor] had already put [2-1/2-year-old son] Preston in the car when Britney locked herself in a room with Jayden," a source tells People. "The cops came and got through the door and tied her down to a gurney."

Spears - who was said to have been under the influence of "an unknown substance" throughout the dispute, but by some new accounts has tested clean of drugs - was taken to Cedars-Sinai where, a source tells Us, she was will be on lockdown for 72 hours as a "special needs" patient, meaning she is believed to "have either overdosed or tried to commit suicide."

What's your take? I think it goes without saying that the time for eye-rolling is over. Britney is sick, and no kid deserves an ill mother. What, if anything, can turn her life around at this point?
