Former Playboy model Anna Nicole Smith is set for a legal battle with the sperm donor father of her baby after insisting he will have nothing to do with the child when it's born. The pregnant widow of billionaire oil tycoon J HOWARD MARSHALL is also refusing to give in to the unnamed father over cash demands from her inheritance. A friend of Smith's says, "She's freaking out because the father wants money and access to the kid. "The guy agreed to get her pregnant and then vanish. Now he wants to get his hands on the inheritance money she is fighting for." Smith is still fighting her late husband's family in court for a $400 million (GBP235 million) share of Marshall's $1.5 billion (GBP880.5 million) estate.
