Kris Jenner‘s mother, Mary Jo “MJ” Shannon, has died. She was 91.

In a post on social media, the Kardashian matriarch shared news that her mother had died on July 16.

“Today, we said goodbye to my beautiful Mommy MJ,” Jenner posted on Instagram. “There are no words that could ever capture what she has meant to me or the heartbreak of having to say goodbye.”

She continued, “My mom was the heart of our family. She taught me everything that truly matters… to love your family fiercely, to be kind, to show up for the people you love, and to never take a single moment together for granted. She taught us that family is everything. She showed us how to love unconditionally and how to find joy in the little moments. She showed me how to face life’s challenges with resilience and faith.”

MJ was featured on E!’s Keeping Up with the Kardashians throughout its run as well as Hulu’s The Kardashians. She was grandmother to Kim Kardashian, Kourtney Kardashian, Khloé Kardashian, Rob Kardashian, Kendall Jenner and Kylie Jenner.

“Mom, thank you for every sacrifice you made, every piece of wisdom you shared, and every moment you loved us so completely,” Jenner said in her post memorializing her mother. “I will miss our daily talks, your smile, your laughter… Our hearts are broken, but we find comfort knowing that love like yours never truly leaves us. Your love will live on in our family, in our traditions, in every moment we are together, and in every life you touched.”

Jenner noted that when she see’s her kids and grandkids, she see’s “pieces” of MJ in all of them, adding, “There is not a part of me that isn’t shaped by you. And if I have done anything right in this world, it’s because I spent my life trying to live in a way that would make you proud. Every memory, every moment, every blessing, it was all because of you, and I will forever thank God every single day for making you my mommy.”

“My heart is broken into a million pieces… thank you for giving me the greatest childhood and oh what a beautiful blessed life… I love you forever Mommy. Thank you for giving us everything,” she ended.
