The couple and their seven kids are "devastated and heartbroken by the loss of their beloved Victoria. They are hurt, deeply wounded and they are grieving. Victoria was a beautiful spirit with a wonderful smile who was greatly loved, and will be deeply missed." She "had a history of seizures and was prescribed medication for this condition. Unfortunately she became dependent and struggled with this condition. She voluntarily underwent rehabilitation and was working hard to address this problem."
Victoria was found unresponsive at about 2 p.m. on Saturday by a housekeeper at the family compound on Green Island Cove in Windermere, Fla. She was transported to Health Central Hospital where she was pronounced dead, according to the Orange County Sheriff's Office. According to the family rep, the Siegel family was attending a wedding in Park City, Utah, when the incident occurred.
They had planned to return to Orlando Sunday, to begin a family cruise on the following Monday. "David and Jacqueline were immediately notified and returned to Orlando the same day," the family rep explained.
E! News confirmed Monday that an autopsy had been performed; the manner and cause of Victoria's death are pending until other test results are received.
Autopsy reports take about 10 to 12 weeks to complete.
"It is likely that Victoria ingested one or more drugs prior to her death," the Siegel family's spokesman said. "However, we cannot determine at this time whether or not the drugs she took were in fact prescribed medication, something else, or where and how these drugs may have been obtained."
Jackie confirmed her daughter's death via Facebook Sunday. "The family is deeply appreciative of the outpouring of support that they have received and request that their privacy be respected while they mourn their loss," the rep said.
The Siegels are perhaps best known for starring in Lauren Greenfield's 2012 documentary, Queen of Versailles, which followed the couple as they built a second 90,000-square-foot mansion, called the Versailles House. They hope to complete it by David's 80th birthday in May 2016. The billionaire couple and their eight kids—including Victoria—most recently appeared on Celebrity Wife Swap June 3.
