The wheels of justice continue to grind slowly for Courtney Love, who managed to get a reprimand from the judge to behave herself.

On Tuesday, reports Reuters, the former Hole singer, 39, was back in a Beverly Hills courtroom, where she is to be tried on felony drug charges stemming from her Oct. 2 trip to a local hospital for what police called “a medical emergency” after she allegedly had broken into the Los Angeles home of her former manager-boyfriend, James Barber.

But the case was again postponed — for the fourth time — by Superior Court Judge Elden Fox, who set a new hearing date of April 15, after Love’s new lawyer, Michael Rosenstein, said he required additional time to prepare his case and obtain evidence from investigators. Love fired her previous attorney in February.

The rocker’s hearing was postponed last time because prosecutors reportedly were awaiting the results of her drug tests.

Wearing a sheer pink-and-red dress and a turquoise sweater on Tuesday, Love, who has pleaded not guilty to illegally possessing prescription painkillers, arrived in court with Rosenstein. She reportedly was two hours late and called out, “Hello, Judge Fox.”

Later, when prosecutors objected to delaying the case, she was said to have blurted out: “I’ve got the bottles with me. I’ve got the prescriptions on me.”

Fox (who is no newcomer to celebrity cases, having heard Winona Ryder’s shoplifting trial last year and Zsa Zsa Gabor’s 1989 assault case when she slapped a Beverly Hills cop) admonished Love not to interrupt, saying: “Ms. Love, you’re not doing yourself any service.”

At one point, says Reuters, Love handed a book, “A History of Women, Renaissance and Enlightenment Paradoxes,” to a reporter seated behind her, pointing out that the table of contents listed female journalists, witches and prostitutes consecutively.

Asked if she would be available for an April 15 court date, Love told Fox: “I’ll be right here.”

According to some reports, when the hearing concluded, Love broke down and was in tears outside the courtroom.

Wednesday night she is due to perform a song from her debut solo album, “America’s Sweetheart,” on “The Late Show with David Letterman,” CBS has announced.
