Zsa Zsa Gabor's daughter Constance "Francesca" Hilton is
preparing for an epic legal showdown with her stepfather, Prince
Frederic von Anhalt, over her ailing mother's estate as the
glamorous socialite-turned-actress finds herself in critical
condition at an LA hospital.  "Frederic has put Zsa Zsa's Bel
Air mansion on the market, but Francesca insists he has no right
to sell the property," a family insider tells me. Why? "He
signed a prenuptial agreement before marrying Gabor."
