Kris Jenner mourns the death of her sister

The Kardashian-Jenner family is in mourning following the unexpected death of Kris Jenner's sister, Karen Houghton. 

Kris shared news of her younger sister's passing in an emotional Instagram post. 

"It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly," she wrote. 

'The Kardashians' star added that her heart aches for her 89-year-old mother, Mary Jo 'MJ' Shannon, and niece Natalie Zettel.

Karen's cause of death has not been revealed. She was 65.

Kris shared several pictures of her sister, including one with her late ex-husband Robert Kardashian.  

She described Karen as "beautiful inside and out". 

"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. She holds such a huge part of my heart and I cherish every single memory we have together."

Kris told her social media followers to cherish their loved ones while alive. 

"Karen’s passing is a reminder that life is so short and precious and tomorrow is never promised. We must tell those we cherish how much we love them. I love you my beautiful sister," the 68-year-old said.

Kris and her sister were estranged in the past. However, the siblings repaired their relationship in recent years. Their mother, MJ, has appeared on the family's reality show on several occasions. 

Kris' children Kim, Kourtney, Khloe, and Robert Kardashian Jr. have a close relationship with their grandmother.

Her two younger daughters, Kendall and Kylie Jenner - whom she shares with Caitlyn Jenner, are also fond of MJ. 

Stars such as Katy Perry and Zoe Saldana sent Kris and her family their condolences. 

"Our hearts are with you. So sorry lady," Zoe wrote.

Katy commented: "Sending you love."

Karen's daughter Natalie also shared a touching tribute following her death.

"Dear Mommy, I can’t believe your gone. This doesn’t even feel real. I keep hoping that I will get to hug you or kiss you or hear your voice one last time. You were my best friend, my everything," she wrote.

Natalie added that Karen was the best mother a daughter could ask for. 

"I'm so grateful to have had a mother like you. You were the most kind, sweet, loving, giving, and caring soul. You had the biggest heart. And I don’t know how to go on without you. It all happened so quick & I wasn’t ready for you to go."
