Kim Kardashian shares heartbreak amid Lewis Hamilton romance

Kim Kardashian is going through heartbreak amid her budding romance with Formula 1 champion Lewis Hamilton.

Fresh off a romantic getaway and vacation alongside the racing icon, The Kardashians star is mourning the loss of a beloved family member.

Her mother, Kris Jenner, announced on Thursday, July 16, that her own mother, Mary Jo "MJ" Shannon, had passed away at the age of 91.

In an emotional tribute, the 45-year-old called her late grandma her "best friend."

“My sweet Grandma MJ, my best friend, my gossip buddy, my forever twin...” she began the heartfelt message alongside a collection of nostalgic photos. “You taught all of us the importance of family, and those values are something we’ll carry with us forever!!!!!”

“You were the woman who showed me what it meant to be a hardworking businesswoman. You gave me my very first job at your store in San Diego and taught me lessons about work ethic, strength, and confidence that I’ve carried with me ever since,” the Keeping Up With The Kardashians alum continued to recall treasured memories. “You always believed in me, championed me, and were my safe place.”

“You truly were the matriarch of our family, and your love is woven into all of us. I know you’re at peace now,” daughter of Kris and Robert Kardashian penned. “Give Papa Harry, Aunt Karen, and my dad a hug for me.”

“You will always be a part of me, I love you soooooo much and I will miss you forever and ever. [white heart emoji] YOU ARE THE BEST OF US!!!” she added before concluding the post with a bittersweet reference, “I know you are up in heaven, looking at all of our Instagram posts of you from your sneaky finsta account you would always use lol.”

The sad news came a couple of days after Kim and Lewis, 41, spent the Fourth of July weekend together in Idaho with her children.
