Deceased former Playboy model Anna Nicole Smith left her entire estate to her dead son, excluding any other heir from inheritance, it has emerged.
Smith died after collapsing in a Florida hotel room
Daniel Smith died last year, aged 20, just three days after Anna Nicole gave birth to her daughter, Dannielynn.
The 2001 will said Smith's long-term companion Howard Stern should hold her estate in trust for Daniel in the event of her death.
Smith, the widow of Texas oil tycoon J Howard Marshall II, died last week.
"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, under her real name of Vickie Lynn Marshall.
Correspondents say the publication of the will has now raised further questions about the future of Smith's estate.
Mr Stern and two other men claim to have fathered Dannielynn.
The lawyer for Smith's estranged mother, Virgie Arthur, said the will was not filed in any court, so it is not valid.
Smith was found unconscious in a hotel room in Florida last week and could not be resuscitated.
An initial post-mortem examination failed to find what caused her death.
But medical examiner Joshua Perper has not ruled out an overdose as a cause, and is waiting for the results of chemical analysis.
A US judge has ordered her body to be kept until a hearing into the paternity of Dannielynn later this month.
Smith married Marshall in 1994 when she was 26 and he was 89. He died a year later.
She spent years in legal battles with Marshall's son for a share of his estate, the Supreme Court ruling in 2006 that she could pursue her case in federal court.
