It wasn't a happy family holiday vacation for Kendall Jenner.

The 17-year-old threw a tantrum on the Greek island of Mykonos this spring while on holiday with her famous family.

The teen broke down in tears because she did not feel apart of the group activities and locked herself in her bedroom.

Peace-maker: Elder half sister Khloe tried to see what was wrong with Kendall

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.

But elder half-sister Khloe 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 she attempts to broker a peace deal she is not met with a friendly reaction from the young model as she enters her bedroom.

The former X-Factor host 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 the teen barks: 'No! Leave, Khloe! Leave! Go away!'

Khloe tells her sister: 'I want to talk to you.'

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

Concerned: Bruce Jenner wants to know what is wrong with his daughter

Approach: Khloe made her way to her sister's room

'I'm not filming this,' she sobs, 'Go away everybody.'

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

Fortunately, back Stateside, this summer Kendall has seemed on good form - recently she was spotted going padle boarding with her half-brother Brody Jenner in Hawaii.

The teen looked in high spirits as she rode the waves alongside her brother while enjoying a family break in the tropical paradise.
