Kylie Jenner may have millions of fans on social media, but it seems she’s lost the respect of one very important person – her sister Kendall.

In a new teaser for season 11 of Keeping Up With The Kardashians, Kendall is seen complaining about her younger sister’s priorities to their concerned parent Caitlyn Jenner.

Kyle seems least bothered

With tensions running high and time running out, Kendall was uncomfortable in her sheer black dress and wanted to borrow something from Kylie’s closet.
When Kendall points out: ‘Because I can’t. We’re going straight from the show,’ Kylie again tells her to just send someone to fetch her a new dress.

‘You’re just literally the biggest f**king b**** I’ve ever met,’ a furious Kendall shoots back, later referring to Kylie as a c***.

Clearly tension in running high between the two close sisters, could it be cause of Kyle spending too much time with boyfriend Tyga?
