“Karen was beautiful inside and out,” Jenner added. “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.”

The mom of six said she cherishes “every single memory” they have together.

“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,” she concluded.

“And it hurts me. I don’t care how much money you have or who you are, you’re my sister. I’m not afraid of her. … I can’t get to her anymore. But I guess it’s the money,” she said.
