Anna Nicole Smith's lawyers are asking for up to another $30 million from the estate of her late husband.
They claim the figure represents the interest she is owed on top of the $88 million she won in court after the death of J Howard Marshall. The former stripper married the billionaire when she was 26 and he was 89.
Lawyer Philip W Boesch says Smith would have earned the interest had she not had to wait for a ruling in the dispute over her late husband's estate.
Smith's stepson, who doesn't want to give any money to her, plans to appeal against last month's initial judgement and any subsequent rulings.
"When their client gets $6 million for every month of marriage and then goes back and asks for more, it's unbelievable," said a spokesman for the stepson, E Pierce Marshall.
Smith, a former Playboy Playmate, whose real name is Vickie Lynn Marshall, met her husband in 1991 when she was working as a stripper.
The couple married three years later, but he died in 1995 aged 90. Before his death, his estate went into a trust that divided his fortune among charities, a foundation, his son and other individuals, but gave nothing to Smith or his other son, J Howard Marshall III.
The judge ruled that Smith had a reasonable expectation that she would receive a portion of her husband's estate.
