Kris Jenner, the adored matriarch of the Kardashian-Jenner family, marked her 69th birthday on Tuesday, with her family taking to social media to share heartfelt tributes. Kim Kardashian led the posts by sharing a nostalgic 1980s throwback photo that captured a special childhood moment with her mother.

“Happy Birthday to the queen of our world, Kris Jenner!” Kim wrote. “I’m so incredibly grateful for the love and support you give each of your children. It’s unmatched, and I’m so lucky to experience such unconditional love. I love you so much, and I’m celebrating you today and every day!”

Khloé Kardashian liked the post, while Kris’s close friend Lauren Sánchez, fiancée of Jeff Bezos, also joined the tributes. Posting a throwback photo, Sanchez wrote, “Thank you for the light and love you bring to everyone around you. I love you so much,” and ended her message with a red heart emoji.

Khloé Kardashian also marked her mother’s special day in her signature, heartfelt fashion, writing, “Singing at the top of my lungs ‘Happy Birthday Mommy!!’ There are no words that could fully express what you mean to me, but I’ll try because you deserve to know. From day one, you’ve been my world, my rock, my greatest source of love. (Along with my daddy) Mommy, without you, there’s nothing. You are everything to me and so much more! You’ve taught me so much—how to love unconditionally, how to be strong when things seem impossible, how to show compassion even when it’s hard. Your wisdom, zest for life, and love are qualities I admire beyond measure. There’s no world or lifetime that doesn’t have you right by my side. Every moment with you is unforgettable!”

She continued, “You make life worth living! You remind me that every day is a celebration! You teach me to live, not just exist. You inspire me to dance as often as I can. You make me believe I can do anything, anytime, and you make life look so fabulous! To the most selfless, beautiful, kind, and loving mommy—Happy, happy birthday!! A huge Martini cheers to my biggest inspiration, the queen of my world! Martini cheers to the life of every party, to the woman who makes me laugh until I cry. The gatekeeper of all that’s sacred and special! Our secret keeper, problem solver, my heartbeat, my teacher, my safe place, my best friend! My entire life, my world, my neighbor for life! HAPPY BIRTHDAY MOMMY!!!”
