Tensions are running high between reality TV stars Kendall and Kylie Jenner. The two youngest members of Kris and Caitlyn Jenner’s brood are having issues with each other, now that Kendall feels like Kylie isn’t prioritizing spending time with her family. In sneak peek videos for upcoming episodes of “Keeping up With the Kardashians,” Kendall openly speaks up about how Kylie chooses her boyfriend, Tyga, and her friends, over her family.

In a video clip shared by E! Online, Kim Kardashian tells her sisters that Kylie invited Tyga to their “all-girls” vacation to St. Bart’s in the Caribbean. Everyone isn’t too happy about it since they all agreed not to invite any men to the trip, even though some of them originally wanted to.

“You could have used this time to be with your family” says Kendall, as she confronts Kylie. The comments however, don’t appear to affect Kylie’s enthusiasm for Tyga’s arrival. She is seen happily squealing as she welcomes him at the airport.

In another video, Kendall reacts negatively again, as Kylie decides to leave early while she and Kendall are spending time with Caitlyn. They appear to be enjoying some time at a race track, but Kylie decides to bail.

“She doesn’t have her priorities straight,” says Kendall, as she tells Caitlyn what happened. Kendall is convinced that Kylie saw an opportunity to leave, when she saw that her sister was there to spend time with Caitlyn. At first, Caitlyn didn’t want to think that way, but she eventually agreed that Kendall is probably right.

Catch the drama between the siblings on “Keeping Up With the Kardashians” Season 11, every Sunday at 9:00 p.m. ET on E!.
