Anna Nicole Smith Estate Denied Windfall

The Anna Nicole Smith estate has been denied the $300 million-plus windfall that she said was promised to her by her late oil-tycoon husband.

The 9th U.S. Circuit Court of Appeals in San Francisco made the ruling Friday, according to the Associated Press, the latest development in the 15-year legal battle over J. Howard Marshall's $1.6 billion estate.

The late blonde beauty, who died in 2007, was involed in a legal battle over the will of her billionaire oil tycoon husband when she died. Marshall passed away at age 90 in 1995, a year after Anna Nicole married him. His son E. Pierce Marshall, with whom Anna Nicole was battling in court, died in 2006.
