Following her death at the age of 65, the youngest daughter of Mary Jo “M. J.” Shannon and Robert Houghton was cremated.

Kris Jenner reacted to her sister’s death by sharing a sweet tribute and praising her as the “sweetest and kindest” person.

“Karen was beautiful inside and out,” the 68-year-old wrote on X March 19. “She was the sweetest, kindest, the most sensitive and vulnerable and so so funny. She always felt grateful and thankful for her life and treasured her family and friends and especially her beautiful daughter.”

Karen’s daughter Natalie Zettel – her only child with ex-husband Mark Zettel – also shared moving words following her mother’s passing, (Karen was married to Zettel from 1996 to 2002).

Due to Karen and Kris having a little bit of a spat at some point, Karen was rarely seen with her famous nieces.

Natalie, 26, also wrote on Instagram March 20, “You were my best friend, my everything. The best mother a daughter could ever ask for and I’m so grateful to have had a mother like you.”
