Anna Nicole Smith, well-known former Playboy model, Trim Spa spokeswoman, and star of her own reality TV show, has died on Thursday, February 8, 2007 after collapsing at the Seminole Hard Rock Hotel and Casino in Hollywood, Florida. Reportedly, a private nurse found Smith "unresponsive" in her sixth-floor room, and promptly called 911. Before she was announced dead, Smith's bodyguard was said to have given her CPR for almost an hour. Anna Nicole Smith's death is the latest misfortune in a string of tragedies experienced by the Smith family. Just this past September, Anna's son and "love of her life" Daniel died in what is believed to be a drug-related death, only days after she gave birth to daughter Dannielynn. Before her death, Smith was engaged in a very stressful dispute over the paternity of her daughter, as Larry Birkhead claims he is the father while Howard K. Stern, Anna Nicole's longtime boyfriend, is listed as the father on Dannielynn's birth certificate. While Smith's life was surrounded by controversy and chaos due to her vivacious (and sometimes peculiar) personality and public battles, it comes as no surprise that Anna's death is receiving the same attention. After all, how does a seemingly healthy 39 year-old woman suddenly just pass away? Even though Anna Nicole Smith allegedly suffered flu-like symptoms and a fever for several days before her death, was this illness the cause of this terrible misfortune? While Smith's autopsy is scheduled for Friday February 9th, toxicology reports very likely will not be available for another couple of weeks. Until then, here are the most current theories about Anna Nicole's death.
