Kendall Jenner: 'Kylie Doesn't Have Her Priorities Straight'

In a new sneak peek from Sunday’s episode of Keeping Up With The Kardashians, Kylie Jenner skips out on quality time with sister Kendall and dad Caitlyn –– but she won’t get away with it this time.

"I actually can't believe that Kylie's leaving right now just because we never get to spend time with each other," Kendall, 20, fumes in confessional. “I travel a ton for work, and even when I'm home in L.A., I feel like I don't really get to see Kylie as often as I'd like to, and to have a moment to spend time with your dad and your sister –– I would take it."

Unfortunately, her little sis doesn't take the bait. Upon Kendall’s arrival to the race car track, Kylie, 18, opts to make her exit from their family day.

"She probably saw the opportunity that you were occupied, and she could go home and do whatever she wants to do,” Kendall later tells Caitlyn. "If I'm being honest, she was here for you and saw that I was here and felt it was her opportunity to leave and go back to being with her friends.”

“I was just curious,” Caitlyn replies. “I didn’t think it was anything I had done, or you had done.”

"She doesn't have her priorities straight," Kendall adds.

Of course, Kylie is known for being a bit of a family flake. Earlier this year, on a Kardashian getaway to St. Barts, Kendall got on her sister’s case for bringing along boyfriend Tyga and ignoring her duties to the "klan."
