Earlier this week, it was reported that Karen died at age 65.

The exact circumstances of her passing are unclear, and county officials attributed her death to natural causes for now. 

Karen was Kris' only sister, with the pair growing up in San Diego together raised predominately by mom MJ after her divorce from Robert Houghton.

Karen is survived by her daughter Natalie, 26, who she welcomed with ex-husband Mark Zettel.

On Tuesday, Kris shared snaps with her beloved sister and wrote: 'It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly.
