At the time of her death, sources close to Scott and Kourtney said that Bonnie's death had brought the couple closer together and had made Scott a "much better father " to Mason, three, and 18-month-old Penelope.
"Scott's been more emotional since his mom died," an insider said. "He's now more dependent on Kourtney. It really affected him. He's staying at home more and being a much better father. Scott has grown up a lot. He's much more responsible."
The father-of-two was raised by his parents in Eastport, New York on Long Island before Scott set off for California in his early twenties.
Jeffrey appeared in a 2011 episode of Kourtney & Kim Take New York, when Kourtney and Scott took young Mason to visit his grandparents in The Hamptons.
