Los Angeles, Oct 27 (IANS): Models Kylie and Kendall Jenner are reportedly upset with their parents Kris and Bruce parting ways. It has affected their behaviour.

Kris and Bruce are ending their 22-year-old marriage and Kendall, 17, and Kylie, 16, are unable to come to terms with it.

"It's not like Kris and Bruce sat down with Kylie and Kendall and discussed what was really happening with their marriage," femalefirst.co.uk quoted a source as saying.

"Kylie still doesn't understand why the two people she loves the most aren't together any more and why they plan on taping their dating lives on 'Keeping Up with the Kardashians'," the source added.

Recently, Kylie allegedly threw tantrums in a hotel.

"Kylie's out-of-control, diva behaviour is a direct result of Kris and Bruce Jenner separating," said a source.

"Kylie has taken her parents split particularly hard and has been having a tough time ever since. She's been acting out and it's her desperate way of trying to bring her parents back together," the source added.
