A source tells Us that the 30-year-old Keeping Up With the Kardashians star flew from L.A. to New York with longtime girlfriend Kourtney Kardashian, 34, to attend the wake on Wednesday, Oct. 30.
Disick grew up as an only child in Eastport, Long Island, New York with parents Bonnie and Jeff Disick.
During his mother's final days, Disick was noticeably absent at several Kardashian-Jenner family gatherings, including Kanye West's over-the-top Oct. 21 proposal to Kim Kardashian at San Francisco's AT&T Stadium. He was also missing from a recent family trip to Six Flags Magic Mountain in Valencia, Calif. to celebrate Kendall Jenner's 18th birthday on Oct. 29. The family rented out the entire park to celebrate the model's special day.
