Love's attorney Michael Rosenstein won a delay of the preliminary hearing after arguing that witnesses needed to be brought in from out of state and that he had not received drug samples for testing.
But the brief proceeding was marked by interjections from Love, who claimed to have prescriptions for the drugs and at another point seemed to fire and immediately rehire her lawyer.
"I have the pill bottles on me," she blurted.
At another point she said to her attorney, "You're fired."
"Miss Love, you're not doing yourself any favors," Superior Court Judge Elden Fox said.
"Rehired," Love said.
Love, former lead singer of the group Hole, is charged with illegal possession of the painkillers hydrocodone and oxycodone.
She was arrested in October after allegedly trying to break into the Los Angeles home of a former boyfriend. Police found the drugs later when paramedics were called to her house after Love suffered a drug overdose.
The judge rescheduled the preliminary hearing for April 15.
Prosecutor Jeff Stodel argued against a delay, saying, "We're ready to go."
