Kendall Jenner yells at Khloe Kardashian during family vacation to Greece

Kendall Jenner threw a tantrum on the Greek island of Mykonos this spring while on holiday with the Kardashian clan.

Kendall Jenner, 17, broke down in tears because she did not feel apart of the group activities and locked herself in her bedroom.

At the start of the clip we see Scott Disick, Bruce Jenner and Kylie Jenner plus Brody Jenner, waiting for Kendall outside on a balcony with stunning views of the Mediterranean.

Elder half-sister Khloe Kardashian says: “Kendall is not at breakfast. Last night she said she felt left behind, and I would never want Kendall to think we didn’t want to hang out with her.”

And when Khloe Kardashian attempts to broker a peace deal she is not met with a friendly reaction from Kendall Jenner as she enters her bedroom.

Khloe Kardashian is firmly rebuked by the teen after she says on video: “If Kendall wanted to hang out with us, the door’s open! We’re your sisters.”

But on seeing Khloe, Kendall Jenner barks: “No! Leave, Khloe! Leave! Go away!”

Khloe Kardashian tells her sister: “I want to talk to you.”

But inside the room Kendall Jenner is seen racing from her chair and storming towards the back door.

“I’m not filming this,” she sobs.

“Go away everybody.”

The full extent and reasoning behind Kendall Jenner’s meltdown will be revealed in an all new an all-new episode of E!’s Keeping Up With the Kardashians on Sunday, August 4, at 9 p.m. EST.
