Keeping Up with the Kardashians star Scott Disick’s mom, Bonnie Disick, has passed away on Oct. 28 at the age of 63. Disick and longtime girlfriend, Kourtney Kardashian, flew to New York to attend her wake on Oct. 30.

Bonnie survives her husband, Jeff Disick. They raised the reality star, 30, as an only child in Long Island, New York.

Us Weekly notes Disick hasn’t been attending any of the Kardashian family’s recent events, such as Kendall Jenner’s 18th birthday at Six Flags Magic Mountain in California on Oct. 29 or Kim Kardashian’s engagement to Kanye West about a week before that. Both he and Kourtney missed Kris Jenner’s 58th birthday celebrations on Tuesday night.

Bonnie and Jeff Disick were featured on an episode of the Kardashian’s E! reality show back in 2011, E! Online reports. Kourtney and Scott, along with sister Khloe Kardashian Odom, took their son Mason to visit their grandparents in New York.

The couple welcomed a second child, daughter Penelope, in July of last year.
