The reality TV star is distraught over the sudden loss of his father, Jeffrey, on January 3, less than three months after his mother passed away from cirrhosis of the liver.
A source close to him told E! News: "[Scott is] very, very sad. The whole family is trying to comfort him. Everyone's upset. To lose both parents so close together, it doesn't seem fair."
Scott and his long-term girlfriend, Kourtney Kardashian - with whom he has Mason, three, and Penelope, 17 months - were seen at Los Angeles International Airport yesterday (05.01.14) catching a flight to New York, where Scott's family is based. It is understood the funeral will take place soon.
Fortunately Jeffrey had been spending a lot of time with Scott and his children before he died, as he had been making frequent visits to see them after the passing of his wife, Bonnie.
The source added: "Scott's dad had been in Los Angeles spending time with Scott, Kourtney and the kids. He wanted to be close to them after the loss of Scott's mother."
Scott is yet to comment on the passing of either of his parents and has not posted anything on social media in 2014. The cause of Jeffrey's death has yet to be released.
