WATCH: Kendall Jenner Says Kylie Jenner ‘Doesn’t Have Her Priorities Straight’

Kendall Jenner isn’t too happy with how her sister has been acting.

In a new preview for an upcoming episode of Keeping Up With the Kardashians, the 20-year-old model airs out her grievances on Kylie Jenner, 18, after discovering that her younger sibling has ditched yet another family function. Speaking with Caitlyn Jenner, Kendall vents about how Kylie should appreciate the time she gets to spend with her dad and sister since all of them are rarely together these days.

“She probably saw the opportunity that you were occupied and she could go home and do whatever she wants to do,” Kendall tells Caitlyn after Kylie opts out of spending family time at the racetrack.

“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 be with her friends,” she continues. “She doesn’t have her priorities straight.”

In a previous clip, Kendall shades Kylie for wanting to spend time with her boyfriend, Tyga, as opposed to her own sisters while on vacation in St. Barts.

Um, can you say drama in paradise?!
