Scott Disick's mother, Bonnie Disick, died Oct. 28 after a long illness, according to recent reports. She was 63.
The cause of death was unclear.
The "Keeping Up With the Kardashians" star, 30, who is boyfriend to eldest sister Kourtney Kardashian, 34, reportedly flew from L.A. to New York with his girlfriend to attend his mother's Oct. 30 wake, according to E! News, Us Weekly and People.
Radar Online, which first reported the story, quoted a source as saying that Disick was "devastated" by the loss because he "was very close to his mother."
The funeral is said to have been a small affair with "just a handful of people," the site reported.
Disick, an only child, grew up in Eastport, Long Island, in New York with Bonnie Disick and his father Jeff Disick. His parents appeared in a 2011 episode of "Kourtney & Kim Take New York," when Kourtney took their son Mason to visit them in the Hamptons following Disick's well-documented struggles with alcohol.
