The reality star, 39, told close friends and family to meet her at the Beverly Hills Hotel for a birthday lunch - before revealing that they would actually be heading to the house that Jenner had shared with late husband Robert Kardashian.
In a video shared on her Instagram stories, Kim could be heard telling the group: “So our lunch is not at the Beverly Hills Hotel today so open up your invites to see where we’re going.”
As soon as her mother read the address, she burst into tears and hid her face with her invitation.
“Big disclaimer - I did not buy it, I rented it for the day,” Kim added in the clip. “I did not buy it, It’s not for sale.”
Sharing an Instagram photo of herself outside the house with her mum and sisters Khloe and Kourtney Kardashian and Kylie and Kendall Jenner, she explained how she planned the special surprise.
“Today we celebrate my mom,” she wrote. “Anyone that knows her, knows how sentimental she is.
“For her birthday I planned a small lunch, with just her kids and her closest friends of 40 + years. I sent out invites with a location where we all met.
“When everyone arrived, I told them I had a surprise and this wasn’t where we would be eating. I then gave everyone the REAL invitation and once everyone saw the address for where we would be going tears filled the room.
“I rented our childhood home. All of our memories live here especially with our dad.It’s where each Kardashian child was born and made us who we are.”
She went on to reveal that she made the “table settings” and “decor” from the “same fabric and print” that the house had previously been decorated with.
Kim also told how she had “rented every car my parents ever owned” and “even remade the exact licence plates.”
She said the celebration was “the most special, nostalgic day of my life and we felt my dad’s presence enjoying this day with us!”
Commenting on the post, Kris said her birthday was “the most magical day” and described her daughter as “an angel to all of us.”
She added: “I can’t express what this meant to me and I will now have this beautiful day to add to a lifetime of the most fabulous memories. I couldn’t bear for it to end.”
Her siblings also praised Kim for the touching gesture, with older sister Kourtney writing: “I can’t stop crying @kimkardashian thank you for planning this for all of us, and @krisjenner for giving us the best childhood.”
Kendall described it as “such a beautiful day” while Khloe described her as “the best daughter EVER.”
