Kendall Jenner Throws Shade At Kylie For Bringing Tyga On Vacation (Video)

In this upcoming Sunday's episode of "Keeping Up With The Kardashians," the family vacations to St. Barts, and it looks anything but relaxing.

The video below shows the Kardashian-Jenner family blowing off some steam on the tropical retreat; although, Jenner brothers Brody and Brandon, along with dad Caitlyn, are nowhere to be seen.

The sneak peek at the two-part vacation episode also reveals Kim telling Kendall, "You know Tyga's coming?" before cutting to an excited 18-year-old Kylie canoodling with her 26-year-old boyfriend on the boat.

Kendall, however, is not cool with her sister's boyfriend tagging along. And when it cuts to a scene of the entire family at the table together, she lets Kylie know it, saying, "You could've taken this time to be with your family."

But it's not just Tyga causing tension on what should be a chill vacation in a gorgeous place. The preview also shows Kourtney flustered over a photo on her phone of Scott Disick with two girls.

In a testimonial, Kim says,

This is the first trip without Scott, he's still causing a problem. I just hope it doesn't ruin the trip.

The drama is already unfolding on yet another Kardashian-Jenner vacation, and we've only seen 30 seconds of it. Tune into E! on Sunday for more.
