You can't hurry Love — but if you're a Manhattan Criminal Court judge, you can still threaten to bust Love for being late.

"I had already issued an arrest warrant," a judge warned Courtney Love (search) yesterday, after the rocker chick showed up at 3 p.m. for her 9:30 a.m. court date on misdemeanor charges of tossing a mike stand at a club last March.

"The rules apply to you as well as everybody else," Judge Melissa Jackson scolded Love, grunge rock's most notorious widow and a spectacle in her own right.

Never one to skulk quietly in and out of court — at her arraignment in May she held an impromptu press conference in the second-floor ladies room — Love again treated the media to her flamboyant style during yesterday's routine appearance.

She showed up with her trademark electrified-straw hairdo, teetering on pink stilettos and wearing a revealing pink vintage cocktail dress. Rhinestones twinkled on the shoes and dress.

Her lawyer, Scott Tulman, and prosecutor David Filer approached the bench to talk to the judge. Normally, this is a time for the defendant to wait quietly at the defense table.

Instead, Love, the 39-year-old widow of Nirvana frontman Kurt Cobain (search) and former lead singer of Hole, kept busy.

The singer — who has had repeated West Coast busts for assault, drugs and breaking into her ex's house — begged the court sketch artist, "Get the nose right!"

She pulled a hard pack of Marlboro reds out of her pink Marc Jacobs handbag (search), and asked a court officer if she could light up. That motion denied, she turned to survey her two rows of press. "You gotta face forward," snapped the sergeant.

Once outside, the garrulous grunge goddess vamped for photographers. "Wild-eyed look!" she announced, adopting same. The shutters fluttered.

Then, in the time it took her bodyguard to hail a taxi, she embellished and signed her court sketch, bummed a match for her Marlboro from a sidewalk hot-dog vendor, dropped the match and bummed a second, and then hinted at — and denied — she was pregnant.

"Do I have a glow on my face?" she teased. "Put it this way, I've got to quit smoking."

Love is due back before the judge Sept. 7 — at 9:30 a.m. sharp. Meanwhile, she remains on probation for an October cocaine bust, and is continuing to fight to regain custody of her 11-year-old daughter by Cobain from her grandparents.
