Anna Nicole Smith's Diaries Sell on eBay for $512,500

Two handwritten Anna Nicole Smith diaries, including one in which she reportedly says, "I hate sex," were sold on eBay for more than $500,000 Thursday night.

A 1992 diary, featuring 26 entries from June 3 to Aug. 16, sold for $282,500. And a 1994 diary, in which she writes, "My husband is very sick and very weak," went for $230,000.

That brings the total to $512,500, not including the 20 percent buyer premium.

Thomas Riccio of Universal Rarities, the California memorabilia house that auctioned off the diaries, said the buyer was a German businessman.

He is "a huge fan" of the former Playboy Playmate, Riccio told

The 1992 diary has a blue cover with the words, "I follow my own star," on it. Inside, Smith says, "I hate for men to want sex all the time. I hate sex," reports the gossip Web site and other gossip sites.

She also reveals she cheated on her late octogenarian husband, Texas oil tycoon J. Howard Marshall II. Still, in the 1994 diary, she writes, "I wait each hour to comfort him with medicines and prayers."

Meanwhile, the National Enquirer and Star magazine are reporting that Smith died with a toxic level of sleeping medication in her system.

The medical examiner investigating Smith's death will release an autopsy report Monday, presumably disclosing what killed the former reality TV star.

Dr. Joshua Perper, the medical examiner for Broward County, Fla., and Seminole Police Chief Charlie Tiger said they will hold a joint news conference to discuss the cause of death.

The conference will take place at 10:30 a.m. EDT Monday outside the Broward County Medical Examiner's Office.

A spokesman for the Seminole Police Department, Gary Bitner, told TMZ the findings at Monday's news conference "are going to be a significant announcement."

"It continues to be a non-criminal, unexplained death," but Perper's findings "are going to provide some resolution" in Smith's death, Bitner told TMZ.

Perper's initial autopsy report showed no immediate indication of a drug overdose and no sign of major external injuries, but a conclusive cause of death has been pending.

The medical examiner delayed the release of the full autopsy report after police gave him additional evidence, though authorities have not said what that is.

Prosecutors have said they are not treating the case as a homicide.

Speculation about what led to Smith's untimely demise on Feb. 8 at age 39 has run rampant since she collapsed in a Florida hotel room and was later pronounced dead at a nearby hospital, with theories ranging from a drug overdose and pneumonia to suicide and murder.

An inquest into what killed Smith's 20-year-old son Daniel in September will begin next week. The official report found that he died of drug-related causes brought on by a lethal interaction of medications.

On Tuesday, a Bahamian judge ordered Smith's baby daughter to undergo a DNA test to determine who is the child's father.

Smith's companion Howard K. Stern and her ex-boyfriend Larry Birkhead maintain they are 6-month-old Dannielynn's father and are fighting for custody, along with her estranged mother Virgie Arthur.

Zsa Zsa Gabor's husband, Prince Frederic von Anhalt, who also claims he could be the baby's father, provided his DNA sample in Los Angeles on Friday.

Results of the comparison of Dannielynn and Birkhead's DNA samples are expected around April 3.

The girl, Dannielynn Hope Marshall Stern, could inherit millions from the estate of Smith's late husband J. Howard Marshall II. Smith had been fighting his family over his estimated $500 million fortune since his death in 1995.
