Former Playboy model and reality-TV star Anna Nicole Smith was met by dozens of photographers and cameramen as she arrived at the U.S. Supreme Court today (Tuesday) to observe arguments over whether state or federal courts had jurisdiction in her probate dispute involving the will of her billionaire ex-husband. Smith was originally awarded $474 million after the death of her husband, J. Howard Marshall II, an amount that was later reduced to $88 million in federal court and then thrown out entirely by an appeals court.
