The Kardashian and Jenner sisters are incredibly competitive, and that was clear in the latest clip from the final season of Keeping Up With The Kardashians. In the latest preview clip for the reality TV series, Kim and Khloe Kardashian teamed up against Kendall and Kylie Jenner for a sisterly game of volleyball. However, there’d already been some intense smack-talking. “Like, I actually know how to play volleyball,” Kendall could be heard saying under her breath to sister Kylie, as Kim and Khloe got warmed up.
“This is very hard to watch,” Kylie agreed. Kendall kept going, telling her two big sisters that watching them play volleyball was “embarrassing.” The tension between the four sisters became a lot clearer when Kim and Khloe opened up in their own confessional. “As siblings, we’re always competitive,” Kim told the camera. “But Kendall has been talking a lot about how the Jenners are genetically gifted and this is something that makes my blood boil,” she admitted.

As Kendall and Kylie got their game plan ready, the clip cut to footage of the two sisters doing cheerleading, snowboarding, and more. They even gushed about Caitlyn Jenner, whom they credited for their athleticism. “My dad just always had so much faith in Kylie and I when it came to being athletic,” Kendall said. “We grew up daddy’s girls with those Olympic genes. The Jenners, we just have it in us.”
