We've witnessed Kendall Jenner grow up before our eyes on our television screens and social media platforms. Over the last nine years, she's gone from a pre-pubescent reality star to one of the fashion industry's most coveted supermodels. Thanks to Keeping Up With the Kardashians (you might've heard of it) and her blog, there are very few moments of the A-list model's life that aren't documented.
Whether she's walking down the hottest runways or snapping photos of her friends, Jenner's constantly on the go. It can be hard to, well, keep up with her, even with the power of social media on our side. So in honor of her birthday, we've put together a list of some of her best moments from the past 21 years. Check them out below.
