Kim Kardashian mourns grandmother MJ; Lewis Hamilton offers support

Mary Jo “MJ” Campbell, 91, the mother of Kris Jenner and grandmother of Kim Kardashian, died in July 2026. Kris Jenner announced the loss on Instagram, describing MJ as the heart of the family. Kim posted a heartfelt tribute, calling her “forever twin,” recalling how MJ gave her first job and taught work ethic, love and resilience. The post included family photos spanning decades.

Lewis Hamilton, Kim’s boyfriend, shared a supportive Instagram message hours later, writing “Hold your people close” alongside images from a recent lakeside vacation in Idaho that featured him with Kim, her children and other relatives. His caption was interpreted as a gesture of comfort for the grieving family.

Kylie Jenner also honored MJ with a private memorial, projecting family photos on a screen and sharing nostalgic images of herself and Kendall with their grandmother. Several media outlets noted criticism over Kim’s vacation post that was scheduled to appear the same day as the death announcement, though she clarified the content had been planned days earlier.

The family’s tributes generated extensive discussion on social media, highlighting the personal impact of MJ’s passing on the Kardashian-Jenner clan and the public’s interest in their private mourning.
