Kendall Jenner Picture

Kendall Jenner is a sibling in the giant Kardashian family. At the age of 13, she signed a modeling contract with a top, worldwide agency. That's not remotely unhealthy.

She's the the oldest daughter of Bruce and Kris Jenner. Kenal has nine siblings in all, including sister Kylie Jenner; half-sisters Kim, Kourtney and Khloe Kardashian and half-brothers Robert Kardashian and Brody and Brandon Jenner.

Kendall, of course, has been featured on Keeping Up with the Kardashians.
