Anna Nicole Smith's 5-month-old daughter and the baby's purported father, Howard K. Stern are staying in the Bahamas mansion where they all lived together before her sudden death last week.

The news comes after a weekend of tumult for the home, as locks were changed twice in less than 24 hours. But as the battle over the mansion continues, the paternity case took a bizarre turn.

The New York Daily News reported that a manuscript of a book written by Stacy Brown on behalf of Smith's half-sister Donna Hogan says Smith froze the sperm of her late husband, J. Howard Marshall II, before the 90-year-old Texas oil tycoon died and may have used it to become pregnant.

But Phoenix Books publisher Henrietta Tiefenthaler, who plans to release "Train Wreck: Anna Nicole Unauthorized" in June, said that manuscript the Daily News reported on was rejected — because Brown never interviewed Hogan.

"The Daily News story, a supposed excerpt from Donna Hogan's book, leaked on February 10, is a hoax. It originated from a rejected manuscript written by Stacy Brown. He did not interview Donna. In fact when Donna first read it, she cried because of the inaccuracies and false statements written on her behalf.

"Not only that; Mr. Brown also plagiarized from numerous other sources and then obviously leaked his version of the manuscript to the press fraudulently. The only copy that exists is in my possession under lock and key and anyone who says otherwise has been duped," a statement from Tiefenthaler said.

Hogan's father refuted the claim, too.

"Where would she get something like that?" Anna and Donna's father, Don, told The New York Post. "Donna has only met her once in her life."

Meanwhile, ownership of the mansion was still up in the air.

Smith, who died in Florida on Thursday, had claimed that a U.S. developer and former boyfriend, G. Ben Thompson, gave her the house. But Thompson said he had only loaned it to Smith — and on Friday had the locks changed.

Smith's lawyer and romantic companion, Stern — one of three men who claiming to be the baby's father — had the locks changed again and on Sunday was once again at the gated waterfront estate, known as "Horizons."

The baby girl, Dannielynn Hope Marshall Stern, was also there, attorney Wayne Munroe told The Associated Press. An AP Television News reporter saw Stern's mother enter the residence as well. Another AP reporter saw Smith's mother, Vergie Arthur, at the gates, but she did not go inside.

Munroe said he has filed a robbery complaint with police over computer equipment, drawings and paintings allegedly taken from the home, and authorities interviewed the housekeeper. Police said Sunday they are investigating.

Munroe said the house now belongs to Stern.

"Right now, Howard is very happy to be reunited with Dannielynn but extremely angry that somebody had the gall to break into Anna's residence," Stern's spokesman, Ron Rale, said Sunday by telephone from Los Angeles.

Smith's ownership of the mansion was the basis of her claim to residency in the Bahamas. In a lawsuit, Smith asked a court to recognize her as the owner and reject Thompson's claim on the house in the exclusive neighborhood. The island chain's Supreme Court has scheduled a Feb. 26 hearing on the matter, Munroe said.

Munroe said the process of authenticating Smith's will could take from a year to 18 months and he declined to name the executor. He said he has not been advised of funeral plans, but that he expected Smith would be buried in the Bahamas alongside Daniel Smith, her 20-year-old son who died there in September.

It was not clear who would get custody of Smith's baby girl, but Munroe said Sunday that she cannot be taken out of the Bahamas without Stern's permission.

Munroe said Stern, who is listed on a birth certificate as Dannielynn's father, was due custody. But two other men have challenged for paternity.

A former boyfriend, Larry Birkhead, has filed a lawsuit claiming he is the father. On Friday, Prince Frederic von Anhalt, the husband of actress Zsa Zsa Gabor, announced that he had a decade-long affair with Smith and he may be the girl's father.

Since Marshall's death in 1995, Smith had been waging a court battle at her death over his estate. A federal court in California awarded Smith $474 million, but that was later overturned. But in May, the U.S. Supreme Court revived her case, ruling that she deserved another day in court.

Experts say the decision of who receives custody could determine the child's inheritance.

Smith gave birth to Dannielynn on Sept. 7 in a Nassau hospital. Three days later, Daniel Smith died while visiting her in the hospital. A medical examiner hired by the family concluded that he died from an accidental combination of methadone and antidepressants, but results of an official autopsy have not been released. An inquest into his death is scheduled to begin March 27.
