Britney Spears has arrived at a courthouse in downtown Los Angeles, where she will ask for overnight visits with her children.

We're told 15 (we counted!) L.A. County Sheriffs' deputies are waiting outside the elevator to escort Britney into the courtroom.

Mark Vincent Kaplan, K-Fed's attorney, has just walked into the courtroom.
