Kendall Jenner Uses Birth Control, Dad Bruce is Not Happy (VIDEO)

Kendall Jenner sure is growing up fast--at least that's what her dad Bruce thinks. In this week's episode of "Keeping Up With the Kardashians", 15-year-old model Kendall is at the center of all of the Kardashian drama when her dad finds out his little girl is using birth control.

As this new clip from Sunday's "Keeping Up With the Kardashians" shows, Bruce was none too pleased when his wife Kris sent him to the local pharmacy to fetch Kendall's prescription.

But Kris ensures her overprotective husband that their daughter is not sexually active--she just has really bad cramps. Looks like it's time for Bruce to have birds and the bees talk with Kendall and her younger sister, Kylie.
