In a manuscript obtained by the New York Daily News, Smith's half-sister Donna Hogan claims her sibling froze the sperm of her 90-year-old oil tycoon husband before his death in 1995.
In forthcoming book Train Wreck, a damning biography about her late sister, Hogan suggests Smith may have used the frozen sperm to become pregnant with baby daughter Dannielynn.
The five-month-old is currently the subject of a paternity battle between Anna Nicole's partner/attorney Howard K. Stern, who is named as the father on Dannielynn's birth certificate, and ex-boyfriend Larry Birkhead, who insists he's the child's biological father.
The prince, a former friend of tycoon Marshall, later backed down on his stunning claim but insisted he did know who Dannielynn's biological father was--and it wasn't Stern or Birkhead.
