Kendall Called Kylie The 'Biggest F*cking B*tch' Right Before The ESPYs (Video)

Ugh, sisters. You can't live with them, but you can't live without them.

That statement definitely seems true for Kendall and Kylie Jenner. In the Season 11 premiere of "Keeping Up with the Kardashians," the world got to see what it's like when things get heated between these sisters.

While getting ready for the ESPYs, Kylie Jenner was not happy to hear Kendall wanted to borrow one of her dresses.

The women were apparently pretty stressed about attending the award show to support Caitlyn Jenner, and tensions were obviously high.

In the clip above, you can watch their argument and hear why Kendall called her sister "the biggest f*cking bitch" before they left for the show. Aren't siblings the cutest?
