Kim Kardashian West has hit out at Caitlyn Jenner for "bashing" Kris Jenner.
The 'Keeping Up With The Kardashians' star blasted her stepmother for saying the 59-year-old television personality had become "less tolerant" of Caitlyn - who was known as Bruce Jenner before undergoing a gender transition - when they found fame through reality television.
In an episode of 'I Am Cait', she said: "You don't have to bash us on your way up!"
Later, the 65-year-old former Olympian and stepdaughter Khloe Kardashian were seen discussing the rift between the former partners.
Caitlyn said: "We really haven't had a chance to talk after you sent me those tough texts."
With Khloe quickly snapping back to say, "When you tried to tell me that I don't know what I'm talking about because ..."
But she was interrupted by Caitlyn, who said: "Because you don't know!"
Meanwhile, a source previously claimed Caitlyn believes Kris has sabotaged her E! reality show.
They said: "Having the same production team involved as 'Keeping Up With The Kardashians' only heightens Caitlyn's suspicions. She feels that everything she is working towards, is now an absolute joke.
"This was the reason sons Brandon and Brody didn't want to participate. They just had this feeling that it was going to turn into a train wreck."
