Reality Star's Sister Dies in Tragic Accident Days After Husband
Queen of Versailles star Jackie Siegel's sister, Jessica Mallory, has died at age 43 from an accidental drug overdose, according to an Instagram post shared by Siegel on Tuesday. The tragic news comes just days after Siegel's husband, businessman David Siegel, passed away.
David Siegel founded Westgate Resorts Ltd., a timeshare resort firm based out of Florida. He and Jackie were the subjects of Lauren Greenfield's 2012 documentary The Queen of Versailles, which documented the Siegels' effort to build the largest single-family dwelling in the U.S., dubbed 'the Versailles House,' just as the country's economy began to tank in 2008.
David Siegel and Westgate Resorts later filed a lawsuit against Greenfield and the Sundance Institute, which produced the film, alleging that the material therein was defamatory. Despite the controversy, the documentary became a sizable cult hit and even spawned a musical adaptation which premiered on Broadway in 2024 starring Kirsten Chenoweth in the role of Jackie and F. Murray Abraham as David. The Siegels also seemed to appreciate their newfound stardom, going on to appear in episodes of Celebrity Wife Swap and Below Deck."As I mourn the profound loss of my beloved husband David Siegel, who passed away on April 5 at the age of 89, my world was shattered again yesterday by the unexpected loss of my beautiful sister, Jessica Mallery, 43, to a scourge we as a family sadly know too well — [an] accidental drug overdose," Jackie wrote in her emotional post.
"Jessica died after using cocaine laced with fentanyl. Her death is another stark reminder of the drug epidemic and fentanyl crisis plaguing our country — and the urgent need to address substance abuse in order to save lives," Siegel continued. "Our work at Victoria's Voice remains more critical than ever, and in her memory, we will continue to raise awareness and advocate every single day until this form of grief is a distant memory in this country."
The Siegels founded the Victoria's Voice Foundation and named it after their daughter, who also died of a drug overdose. 'Victoria's Voice seeks to be the trusted national leader in successfully educating and providing the necessary tools for parents and families to take action to prevent substance use disorder and overdose deaths,' its website reads.
"To say we are devastated is an understatement,' Jackie wrote of David's passing just days ago. 'But I find comfort in knowing that Victoria was there to greet him — the first thing he heard was 'Dad,' followed by a big hug."
