The exact cause of the celebrity child's death is still unknown as the medical examiner was still determining the cause and manner of her death. 

"It is with great sadness that we ask you to respect our privacy during this tragic time and the loss of our beloved daughter, Victoria," wrote Jackie, who was the main subject of the award-winning 2012 documentary.

The Seigels became notoriously famous after the release of Lauren Greenfield-directed documentary, which showcased their attempt to build the self-proclaimed largest home in America. The 90,000 sqft project, which started in 2004, was stalled for a couple of years due to the failing economy. The construction has started again and the house is going to complete by 2016, Daily Mail reported.

Following the release of the documentary, the couple became known for their extravagant life style that included a personal staff of 30 people, including a driver, cook, house manager and a hair & make-up person.

The couple recently appeared on the ABC's "Celebrity Wife Swap," during which it was revealed that they do not spend much time with their kids, who are being taken care of by the hired staff. Jackie even admitted that she is not well versed in baby handling despite being a mother of eight kids.  On the other hand, it appeared that David remains engrossed in work all the time and hardy sees his children.
