Kendall Jenner slammed her sister Kylie for taking Tyga on their family vacation.
The 20-year-old model was furious when her younger sibling decided to bring her boyfriend along on the trip to St. Barths.
In a teaser for the upcoming two-part special of 'Keeping Up With the Kardashians' after older half-sibling Kim Kardashian West revealed Kylie's plans, Kendall fumed: "You could have taken this time to be with your family."
This isn't the first time a row has broken out between the sisters in recent months.
On the season premiere of the show, Kendall got angry when Kylie refused to let her borrow a dress.
She blasted: "You're just literally the biggest f***ing b**h I've ever met."
And when her father, Caitlyn Jenner, asked "what's the deal with Kylie?", Kendall said: "She doesn't have her priorities straight and I tell everyone that."
However, the model recently insisted she and her sister rarely argued.
She wrote on her website: "We'll occasionally argue with each other and say horrible things, but definitely not on the level that it used to be, lol. We've always remained close, but over the years the two of us have just matured."
