Kim Kardashian West and Khloe Kardashian have threatened to axe their sister Kourtney from the family’s reality show during Sunday’s dramatic episode.

The “Keeping Up With The Kardashians” star has hit out at her sister in Sunday’s episode of the programme for avoiding opening up about certain aspects of her personal life and being “so secretive”.

She ranted: “Kourtney spends a lot of time off camera. She won’t talk about her relationship, but you’ll see paparazzi photos of her and her guy that I can’t say his name on the show because Kourtney doesn’t want to.

“I’ll see things or read about it online and wonder like, did this really happen? Is she talking to this person?

“And realise that it’s true, but she’s so secretive with us that she won’t even tell us.”
