Full disclosure: we've been watching Keeping Up With the Kardashians since it first aired, but we hardly expected one of Kim's little sisters to be high-fashion runway model someday. Still, in the years since, Kendall Jenner has proven that she's not trying to keep up with anyone in her family — she's making a name for herself. And, as one of the year's most in-demand models , she's taken the runway for everyone from Karl Lagerfeld to Balmain  — making it hard to believe she's just celebrating her 19th birthday. So, in honor of her big day — and her very big year — we're reliving the moments that proved that Kendall was destined to be so much more than Kourtney, Khloe, and Kim's little sister. Take a look.
