Police released Tuesday a tape of the dramatic phone call from officers seeking assistance for a stricken Anna Nicole Smith, who was discovered moments earlier in her hotel room "not breathing ... not responsive."

In the 31-second call, Seminole, Fla., police ask Hollywood, Fla., paramedics for help in assisting Smith, who was found unconscious in her room at the Seminole Hard Rock Hotel and Casino on the Seminole Indian tribe's reservation.

The tape plays as follows:

"The is Seminole police ... if you could please respond to the Hard Rock room 607, it's going to be in reference to a white female. She's not breathing and she's not responsive ... she's actually Anna Nicole Smith."

Officials say they were on the scene six minutes after the call. Smith, a former Playboy playmate, model and reality TV character, was pronounced dead about an hour later at a hospital.

The initial emergency call to the Seminole Police was not released; the Seminoles are a sovereign Indian nation and not subject to state open government laws.

Smith died on Thursday of unexplained causes, leaving behind a three-way paternity dispute over her 5-month-old daughter, who is potentially worth millions.

Meanwhile, Dr. Joshua Perper, the Broward County medical examiner who performed the autopsy on Smith, wants to release her body to the legal next of kin as soon as possible, he told FOX News.

Perper faxed an affidavit to an attorney representing Smith's companion, Howard K. Stern. The attorney is expected to take the affidavit to the Broward Clerk of Courts to get a court order releasing the body to Stern.

Perper will not release the body without a court order because of public interest and the fact that more than one person may attempt to claim the body.

In other news, Smith checked into a drug-detox program while she was pregnant, her former boyfriend claims in explosive court papers.

Larry Birkhead claims the former Playboy Playmate admitted herself to Los Angeles' Cedars Sinai Hospital in April 2006 — and was discharged May 5.

The allegations were made in court documents — filed in Nassau Supreme Court — that contest her daughter's paternity.

Birkhead, a photographer who is one of several men claiming to be Dannielynn Hope Marshall Stern's father, says he was at Smith's side — and even slept in her hospital bed each night — as she tried to get off drugs.

But by the end of May, Birkhead claims, the pair was having problems because Smith refused to give up drugs before giving birth.

Birkhead filed the court documents Jan. 30. He is seeking to have Stern's name removed from Dannielynn's birth certificate.

Immigration Allegations

Smith had a fling with the Bahamian immigration minister to protect everything dear to her — her baby daughter, the hundreds of millions the child could inherit and an island home worth $900,000 that Smith had gotten for free, according to new charges.

Smith slept with Shane Gibson, who fast-tracked Smith's residency in August 2006 — a month before baby Dannielynn was born, a political opponent charged.

Meanwhile, in a local TV interview, Gibson denied that his friendship with Smith led him to fast-track her residency application.

The interview was broadcast late Monday, hours after photographs of Gibson and Smith embracing in her bed with their clothes on appeared on the front page of The Tribune of Nassau.

Stern backed up Gibson, saying Gibson's family supported Smith after her son died.

"They came to the house to pray with us on too many occasions to count," Stern said in a statement.

A worker for the Bahamian opposition party said Gibson blabbed to anyone within earshot how he bedded Smith.

The Nassau Tribune claimed to have considerably more intimate photos, which were being sold to media outlets in the United States.

Ingrahm Ivone, a public-relations consultant and researcher for the opposition, claimed there also were e-mails proving they were sexually involved.

Wayne Munroe, one of Stern's lawyers, said Stern took the photos at Smith's 39th-birthday party in November.

He explained that Smith didn't get out of her bed for the celebration — and greeted everybody with a kiss.

"I notice [Gibson] has his clothes on in every photo," Munroe said. "I see nothing in them."

Stern's lawyers also said the photos were swiped from Smith's Bahamian home by real-estate developer G. Ben Thompson — Smith's boyfriend after she broke up with Birkhead — who had demanded the return of the luxury home.

They say photographs, drawings, paintings, a computer and Dannielynn's birth certificate were all stolen in a raid orchestrated by Thompson.

Thompson denied the accusations.

By Smith's claiming residency in the Bahamas, her lawyers say, any custody hearing over Dannielynn must take place there.

Munroe also argues that a paternity suit can be fought out only in a Bahamian court because Dannielynn is listed as a resident on her birth certificate.

Under Bahamian law, the court would lock up Dannielynn's likely inheritance from Smith's late husband, oil tycoon J. Howard Marshall II — as much as $474 million — until she was 18. That would mean the man who is eventually proven to be Dannielynn's daddy wouldn't be able to touch a cent without a court order.

Meanwhile, Bahamian cops — already probing the overdose death of Smith's 20-year-old son, Daniel, in September — are now interested in the break-in at Smith's house.

The cops questioned Stern about it Monday, as well as about a photograph that surfaced over the weekend showing Smith had a bottle of liquid methadone stashed in her fridge.

Munroe countered that Daniel died from overdosing on methadone tablets — not the liquid form.

Ford Shelley, Thompson's son-in-law, said he was the one who found the methadone when he went to secure the house the day after Smith died in Florida.

Stern and Anna

Meanwhile, Stern's sister said he was not with Smith when she died, but he knew she was very sick.

Stern had told his sister that Smith was running a fever of 105 degrees shortly before her death on Thursday, and that a nurse was "icing her down" earlier that day at the Seminole Hard Rock Hotel and Casino in Hollywood, Fla.

Bonnie Stern, who recently traveled from her Beverly Hills home to the Bahamas to comfort her brother, said that Stern had tried to get Smith to visit a doctor but Smith had refused because she was afraid that it would draw publicity.

"They had plans to get a yacht and to buy an engagement ring. They were going to get married Feb. 27. It was going to be a real marriage," she said.

Asked what she thought caused Smith's death, Bonnie Stern said: "Her immunity was so low. She was so depressed. She kept getting sick and her body just probably broke down."

Smith had never recovered from the loss of her son, Daniel, who died in the Bahamas in September while visiting his mother and newborn half-sister at a hospital, friends said.

Smith had met Stern in 1996 when she was referred to his law firm, Bonnie Stern said.

"He started doing her legal work and then he became her confidant. They became best friends and then he fell in love with her," she said.

Stern, 38, said in an interview with "Entertainment Tonight" that he is the executor of a will drafted for Smith that will leave everything to the little girl, Dannielynn.

As for Birkhead, Bonnie Stern said, "there were times of some intimacy" between Birkhead and Smith, but said, "Larry Birkhead was not her boyfriend."

Actress Zsa Zsa Gabor's husband, Prince Frederic von Anhalt, recently said he had a decade-long affair with Smith and that he too might be the baby's father. Von Anhalt said Monday that he plans to file a paternity challenge in court and wants a DNA test.
