Kris Jenner goes online to admit confusion over daughters’ births

While they’re both incredibly beautiful women who boast long dark locks and stunning smiles, that seems to be where the similarities end between famous siblings Kourtney Kardashian and Kendall Jenner.

In fact, they famous pair are so dissimilar in stature, even their mum, Kris, finds herself astounded by the difference from time to time.

Taking to Instagram to highlight her confusion yesterday, the mum-of-six uploaded a shot of her two daughters standing side by side and, we’ll be honest, the height different is seriously something!

Paying tribute to both her daughters' unique looks, Kris wrote: “Not sure how this happened but I gave birth to both of them… #legs #love #familyfun #beautycomesindifferentshapesandsizes #blessed.”

Bare-legged and wearing only white shirts, the famous sisters reminded the world just how different siblings can be as Kendall towered over her older sister Kourtney, who stands at just 4 foot 11 inches tall, in a photo which has amassed over 300,000 likes in less than 24 hours.

Although to be fair, 19-year-old Kendall, who stands at five foot 10 and a half inches in her bare feet, hadn’t kicked off her towering stilettos before the impromptu shot was taken, so it's only fair they pose for a do-over, if only to help clarify things for their baffled mum!

Now, let's all take a moment to appreciate those stunning Kardashian/ Jenner pins.

Sigh.
