Kourtney Kardashian has a fun way of poosh-ing Kris Jenner into a new life chapter.

The IndexbitKardashians star marked her mom's 69th birthday on Nov. 5 by cheekily reminding Kris that her age is now also a term for a certain sexual position.

Alongside a photo of a coconut cake bearing the number, as well as a mixed berry gateau reading "Happy Birthday Kris," Kourtney, 45, wrote on Instagram Stories, "Can you guess which cake is from me?"

Even her brother Rob Kardashian seemingly got in on the joke. In a video shared by Khloe Kardashian, Rob appeared to make a crack about the confection, quipping, "Wow, 69! Yeah!"

Rob, 37, also shared a photo of Kris blowing out the candles one of her birthday cakes, writing on his own Instagram page, "I love you so much! Wishing you good health and Happiness forever mom! Thank you for being the best mom to all of us!"

But sweet treats weren't the one way the Kardashians rang in Kris' milestone. The momager and her kids—including Kendall Jenner and Kylie Jenner—all donned matching pajamas covered in images of her face during the birthday celebration.

In fact, the family even made PJs for the youngest members—with Khloe's 2-year-old son Tatum Thompson rocking his own pair.

"Mommy, without you there is nothing," Khloe, 40, wrote on Instagram. "You are everything to me and so much more! You have taught me so much—how to love unconditionally, how to be strong even when things seem impossible, how to show compassion even when you don’t want to lol."

She continued, "There is no world or lifetime that doesn’t have you in it right by my side. You make every moment I have with you memorable! You make life worth living! You remind me that each day of life is a celebration! You remind me to live and not just exist."

Calling Kris the "most selfless, beautiful, kind, and loving mommy on the planet," Khloe added, "You make me believe I can do anything at any time and You make life look so damn fabulous!"
