His mom Bonnie Disick died suddenly at age 63, according to RadarOnline. "Scott was very close to his mother," a source said of the 30-year-old only child, adding that Scott's "devastated" by her death.
Scott traveled from LA to New York to attend her funeral on Long Island with girlfriend Kourtney Kardashian by his side.
"It was a small affair. There were just a handful of people. No other Kardashians beyond Kourtney attended," the source tells Radar.
At least the couple got to enjoy a relaxing getaway shortly after her sad passing. Days after the funeral, Scott and Kourtney vacationed in the Dominican Republic at the Breathless resort grand opening.
Scott has yet to comment on his mom's death on social media, but he shared video of Kourtney dancing with the band, saying: "Dominican dance off."
