Scott Disick is mourning the loss of not one, but two parents.
Following his 63-year-old mom Bonnie's passing in November, Scott's dad, Jeffrey Disick, died Friday, E! News has confirmed.
Further details about Jeffrey's death have not yet been revealed, but a source tells E! News the real estate developer was in Los Angeles at the time of his passing.
Bonnie and Jeffrey Disick appeared on a 2011 episode of "Kourtney & Kim Take New York" when Kourtney Kardashian took Mason to spend time with his grandparents in the Hamptons.
"The whole family is so devastated and Scott is beside himself," a source told E! News. "Scott is an only child with no remaining family."
Since his dad's passing, Scott has not posted to his social media accounts, nor has he released a comment regarding his father's passing.
Scott and Kourtney were last spotted together in Park City, Utah, with the rest of the Kardashian-Jenner clan on a family holiday vacation on New Year's eve.
