The youngest of the Kardashian-Jenner brood — sisters Kylie Jenner and Kendall Jenner — have drastically shot to superstardom in the past year, going from cutesy little sisses on E!'s Keeping Up With The Kardashians to professional models and scandal-starting tabloid darlings. (We'll let you figure out which one's which.)

Kendall's transformation from pre-teen to drop dead gorgeous fashion fixture has been fascinating to watch over the past few months, as she's continued to refine her look and take on high fashion gigs. From walking the runway for Marc Jacobs, Michael Kors and Givenchy to snagging Vogue covers across the world, Kendall has legitimately built herself a sturdy — and surely lucrative — career as a model. She's not the only one bringing in the dough in that family! (And have you checked out her new lifestyle app yet?)

We're taking a look back and documenting Kendall's journey over the years through photos. Check out the gallery above!
