Courtney Surrenders!

Welcome back, Courtney Love.

The embattled rock star, who has shunned the spotlight since entering an "institution" on the East Coast last week, quietly turned herself in to a Los Angeles police station on Friday in connection with an arrest warrant issued earlier this month after she skipped an arraignment hearing on a felony assault charge.

At around 12:45 p.m. Love surrendered to the Los Angeles Police Department's Wilshire station, according to a police spokesperson, where she was booked and then bailed out within a half hour for the hefty sum of $150,000.

"She was very cooperative throughout the entire process," said Capt. Patrick Findley of the LAPD's Wilshire Division.

She will remain free until Aug. 20, when she's due to be arraigned on an assault charge stemming from an alleged April attack on another woman at the Los Angeles home of Love's ex-boyfriend and onetime manager.

Los Angeles Superior Court Commissioner Dennis Mulcahy initially issued the warrant for the MIA Love on July 9, saying at the time that he found "no legal excuse" for her failure to appear on a "serious matter."

Love's defense lawyer, Michael Rosenstein, said his client was a no-show because she was confused about whether her presence was required at the hearing in Los Angeles. That same day, Love's 40th birthday, she was rushed to a New York City hospital for what Rosenstein called "an emergency gynecological condition."

Mulcahy subsequently refused Rosenstein's request to suspend the warrant.

In response, Rosenstein announced he planned to smuggle Love into the state and deliver her to authorities to spare her the potential embarrassment of being busted in public.

Mission accomplished.

Dressed down in jeans, a smiling Love finally surfaced for booking on Friday. According to broadcast reports, her camp had told the news media that she would be turning herself in downtown L.A. later in the afternoon, but instead showed up an hour earlier in a different station, apparently to give reporters the slip.

Love now has a busy week ahead of her.

On Friday, another judge ordered the erratic rocker to appear at a hearing in Beverly Hills next Thursday to face two felony counts of illegal drug possession.

"Your client must be present," Los Angeles Superior Court Judge Elden S. Fox told Rosenstein early Friday, nixing a waiver that allowed the legal eagle to appear in Love's place at procedural court hearings.

Until then, the rocker, who has pleaded innocent to the drug charges, can remain free on her recognizance , despite prosecutor's efforts to set bail at $40,000.

Meanwhile, now that she's back on the West Coast, she has 24 hours to appear before another judge for sentencing in yet another case.

Last week, Superior Court Judge Patricia Schnegg gave Love one business day after leaving the East Coast facility to turn up in Schnegg's courtroom. That means Love will most likely appear on Tuesday to learn her fate.

Schnegg is expected to order Love into a drug-treatment program in response to the singer's guilty plea in May to a misdemeanor count of being under the influence of cocaine during a window-smashing spree outside an ex-boyfriend's house last October.

The America's Sweetheart singer's whereabouts had been largely unknown since she checked out of New York's Bellevue Hospital last week.

Robert Rigg, one of Love's legal coterie, would only say that love had been appointed a legal guardian and was in a New York-area "institution." But, according to E! Online columnist Ted Casablanca, Love spent last week in a rehab center in Connecticut. Casablanca says that Love's insurance didn't cover the stint in Connecticut and that she was going to transfer to another facility in Orange County, California.

Love's camp apparently feels that the voluntary stay in rehab could be viewed favorably by the judges in Love's various plights.

It is not immediately known whether Love entered the new facility Friday.
