LOL We tried to explain and show her that it was just daddy but she didn’t get the concept yet! So shout out to the photographer for editing her in & making our family Flinstones dreams come true!" the mom of four explained on Instagram.
Kourtney kind of has a thing for dressing up as the hottest ladies in music, and 2019 was no exception when she sparkled and shined as Spacey Kacey.
