(Yahoo!) - Scott Disick is in mourning following the death of his mother, Bonnie, on Oct. 28.

Reports are conflicting as to whether she was ill for some time or if the 63-year-old grandmother's death was more sudden. She and her husband Jeff lived on Long Island, New York, which is where Scott, their only child, had grown up.

Scott, who had been spending more time with Bonnie during her final days, missed several recent Kardashian-Jennerfamily gatherings, such as Kim and Kanye's engagement in San Francisco on Oct. 21 and Kendall Jenner's 18th birthday blowout at Six Flags Magic Mountain on Oct. 29. It seems that he and Kourtney had flown to New York to attend Bonnie's wake on Oct. 30.

Though Scott's parents lived far from their entrepreneur son, they did appear on a 2011 episode of "Kourtney & Kim Take New York" when Kourtney and Khloé took Mason to visit the Disicks in the Hamptons.

While in New York, Kourtney has been busy promoting the Kardashian Beauty product line, but she and Scott have been spotted out together as well. They were snapped taking a stroll while holding hands and making a visit to the Kardashian's DASH boutique in Soho. As of now, Scott has not yet commented publicly on his mother's death, though it appears Kourtney is doing her best to help him through it.
