Mark "Hollywood" Hatten used to date Anna Nicole Smith. Yeah, yeah. We know. Didn't we all. But his allegations are much more scandalous than that.
The FBI believed Anna Nicole Smith schemed to kill her late husband's son to secure his family fortune, and investigated her for it from 2000-2001.
Ultimately, they did not have enough evidence to charge the Playboy model.
"I'm responsible [for the probe]," Hatten told the New York Daily News.
The late model and reality star was investigated for plotting the murder of E. Pierce Marshall, who was in a legal battle with her over her dad's $550 million estate.
J. Howard Marshall, who made a fortune in oil exploration during the 20th Century, died in 1995 at age 90. He was married to Anna for his final 14 months.
Hatten says Smith wanted him to off his son to secure the money - and wanted him to do the honors: "She was begging me to kill Pierce Marshall, telling me that he was the Devil standing in the way of her inheritance."
"She said that we'd be set if I just take this gun and knife and do this. She convinced me she wanted [Pierce Marshall] dead. But she was doped up."
"Then we'd wake up the next day, and she'd say, 'No, no, I don't remember saying that.' It was like a split personality," her ex reflected.
Mark "Hollywood" Hatten said he feared what would happen so he went to Marshall's lawyers. No direct evidence of Smith's involvement appears in the FBI file.
Agents confiscated a .375-caliber Smith & Wesson revolver, a knife and a Dr. Seuss hat (?) that Hatten said was the hiding place for the weapons.
Smith's lawyer, Ron Rale, said the allegations are untrue.
Pierce Marshall died from natural causes three years ago. Smith died of a drug overdose in 2007, for which her former companion Howard K. Stern and Drs. Khristine Eroshevich and Sandeep Kapoor were only recently charged.
Smith's death has been called a "pharmaceutical suicide."
