Jeffrey Disick was in Los Angeles when he passed away on January 3.
"Scott's dad had been in L.A. spending time with Scott, Kourtney and the kids," a source tells E! News. "He wanted to be close to them after the loss of Scott's mother."
There is no word yet on why the 63-year-old died and Scott, who is obviously devastated, is yet to comment on the situation.
Although Scott was an only child, he has built his own family, with Kourtney Kardashian, their two kids and the rest of the Kardashian clan, who will hopefully rally around him during this incredibly difficult time.
Scott was last spotted at Los Angeles International airport and was believed to be flying back to his home state of New York.
