April 21 (UPI) -- Caitlyn Jenner is mourning the death of her mother, Esther Jenner.
The Olympic gold medalist and former Keeping Up with the Kardashians star announced Friday that her mom died Thursday morning at age 96.
Jenner shared the news on Instagram alongside a tribute to her mom.
"I am heartbroken to announce my mom passed away yesterday morning, peacefully. Losing a mother is unique in the sense that she is the only person that loved me my entire life," Jenner captioned the post.

Esther Jenner appeared on Keeping Up with the Kardashians in 2013 and also made appearances on Jenner's series I Am Cait and Untold: Caitlyn Jenner.

"I love her," she added. "And she's happy. That's all that matters."
