Scott Disick, 30, is mourning the loss of his mother, Bonnie Disick.
Disick, who has two children with reality star Kourtney Kardashian, lost his mother last week, People magazine reports. She was 63.
The cause of death has not been reported, only that Bonnie and her husband, Jeff Disick, raised their son, Scott, as an only child on New York's Long Island.
People adds that Disick and Kardashian, 34, flew to New York to attend the small funeral, also last week.
Kardashian and Disick have been together since 2006 and had their first son, Mason, in 2009. In 2012, they added daughter Penelope.
