In news so tragic it probably brought the self-proclaimed Lord Disick to his knees, 'Keeping Up With the Kardashians' star and Kourtney Kardashian baby daddy Scott Disick is mourning the sudden death of his father.

Radar Online reports that Disick's father, Jeffrey Disick, passed away last week, less than three months after his mother died at age 63. It isn't yet known what took Jeffrey's life, and Scott has yet to comment on the passing of his father, remaining silent on social media and in the press.

Jeffrey and wife Bonnie raised Scott in Eastport, Long Island, New York until he moved to Los Angeles and became a "satellite Kardashian."

Jeffrey and Bonnie made a handful of appearances on various Kardashian-central programs, but generally kept their own lives out of the spotlight. The Kardashians have yet to comment on the loss.

Our thoughts are with Scott and his loved ones during this sad time.
