Scott Disick's mother dead, Bonnie Disick of Eastport was 63, reports say

Bonnie Disick of Eastport, the mother of Scott Disick, "Keeping Up With the Kardashians" star and boyfriend to Kourtney Kardashian, has died at the age of 63.

Several sites including US Weekly and E!, the network that airs the "Kardashians" reality show, reported the news Thursday. E! called her passing "sudden," while US reports she died following a long illness. The grandmother to Scott and Kourtney's children, Mason, 3, and Penelope, 1, died last week, according to People.

Bonnie Disick appeared on early episodes of the Kardashians' spinoff show "Kourtney and Kim Take New York" in 2011, when Kourtney and sister Khloe take Kourtney and Scott's son, Mason, to visit his grandparents on Long Island.

On the current season of "KUWTK," Scott Disick, 30, revealed he struggles with being around death and illness, in part because his father, Jeff, suffers from diabetes and heart problems. In that episode, he put his fears aside to spend time with a fan who had cancer and wanted to meet him.

Kourtney and Scott reportedly attended Bonnie's wake Wednesday, as well as a "small" funeral in New York.
