"Not sure how this happened but I gave birth to both of them," Kris, 59, captioned an Instagram photo, appearing to be at a photo shoot. She added: "#legs #love #familyfun "#beautycomesindifferentshapesandsizes #blessed."
In the hilarious pic, model Jenner, 19, towers over the mom of three, 36, thanks to black high heels. They both kept the sleeves rolled up and wore their dark locks down.
"We're sexy and we know it," Kardashian teased in a silly Instagram video. "I'm gorgeous."
