The 18-year-old daughter of David and Jackie Siegel -- who were featured in the 2012 documentary "Queen of Versailles" -- was found dead Saturday in their Florida home.
Victoria Siegel -- the oldest of 8 children the Siegels have together -- was found unresponsive in the family's Windermere mansion just after 2:00 PM. She was pronounced dead at Health Central Hospital.
So far, investigators have no ruling on the cause of death.
Jackie Siegel said the family would release more information about Victoria's death ... but for now she had "no comment."
In addition to the documentary about their financial struggles to build a 90,000 square foot mansion, the family was featured recently on "Wife Swap."
