Jenner Sisters: Kylie and Kendall Then
When their family’s reality show, Kylie and Kendall, premiered on MTV in 2007, the world was introduced to Kylie and Kendall. They were known for their unruly hair, cheeky looks, and questionable parental supervision at the time of their birth.

Kylie and Kendall Jenner are the children of Kris Jenner, a reality television star, and Caitlyn Jenner, a former Olympic athlete. The Jenners also have Caitlyn’s other children, including reality personality Brody Jenner, in addition to the Kardashians who are their biological siblings. The daughters grew up in Calabasas, California, and were eventually both homeschooled as teenagers. Kendall began her modelling career when she was fourteen years old.
