FORT LAUDERDALE, Fla. - Anna Nicole Smith said in a 2001 will that all property of her estate should be given to longtime companion Howard K. Stern to hold in trust for her son, who has died, according to a document released Friday.

The document said the former Playboy Playmate's estate should be held in trust for son Daniel Smith, who died last year, three days after Smith gave birth to a daughter.

"I have intentionally omitted to provide for my spouse and other heirs, including future spouses and children and other descendants now living and those hereafter born or adopted,'' Smith said in the will.

Stern and two other men claim to have fathered Smith's daughter, Dannielynn.

The will did not say where Smith wanted to be buried, but named Stern as her executor.

The lawyer for Smith's estranged mother, Virgie Arthur, said the will wasn't filed in any court, so it is not valid.
