ANNA NICOLE SMITH - COULD DEAD OIL TYCOON BE DANNIELYNN'S DAD?

COULD DEAD OIL TYCOON BE DANNIELYNN'S DAD?

A fourth father has entered the paternity battle over ANNA NICOLE SMITH's baby daughter DANNIELYNN - the model's late husband J. HOWARD MARSHALL. 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. On Friday (09FEB07) - the day after Smith passed away in Florida - ZSA ZSA GABOR's husband PRINCE FREDERIC VON ANHALT came forward, claiming he could be the father of the child. 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.
