Every “Keeping Up with the Kardashians” fan is familiar with “The Lord.” He’s the suave, impeccably dressed, free-spirited and witty Scott Disick everyone loves to watch. However, for the past week, he’s been a bit out of character, in a relatively somber state due to the devastating loss he just experienced.

The reality TV star is mourning the sudden death of his mother. RadarOnline reported on Thursday that Bonnie Disick has died at the age of 63. As of now, no detailed reports have been released on what may have caused her untimely death. She and Disick’s father, Jeff, resided in Eastport, Long Island, N.Y. He was their only child.

The media outlet also reports that Disick and his long-time girlfriend, Kourtney Kardashian, flew from Los Angelos last week to attend the private funeral. The couple has been in New York since receiving the devastating news. The couple has been spotted several times in New York over the past week.

Some may remember Disick’s mother when she and her husband made short appearances on the KUWTK spin-off, “Kourtney & Kim Take New York.” During that episode, Kourtney, and her sister, Khloe Kardashian-Odom took Mason to visit his paternal grandparents.

Disick and Kardashian have been dating since 2006. They have two children together; a son, Mason, 3; and a daughter, Penelope, 1. He has not yet released any statements in response to his mother’s death.
