Kim, Khloe and Kourtney Kardashian have reportedly 'turned their backs' on Caitlyn Jenner.
Caitlyn, who was previously known as Bruce, was married to their mother Kris Jenner for 22 years before splitting in 2013. The couple also have two daughters Kylie (18) and Kendall (20) together.
And while the famous family have put on a united front on social media, it's believed to be a tough topic behind the scenes, with viewers getting a sneak peek of the tension on E!'s I Am Cait watching Kim and Khloe slam the Olympian for her scathing interview in Vanity Fair.
"There's not a lot of love for Caitlyn," an insider told Us Weekly.
"Vanity Fair was the start of the downfall. It came out and they looked like idiots, they first saw the article on Twitter."
"The Kardashians were furious once they realized she took jabs at Kris, a lot of times she wasn't very nice,' an insider shared.
"They are so incensed that they may be done with Caitlyn for good. Everyone has turned their backs on her."
The media moguls are said to be angry because the 65-year-old owes her reality tv career to her ex-wife.
"Theyy feel Caitlyn needs to understand that the platform she has now, and her money, are because of Kris. She had nothing before Kris. Don't bite the hand that fed you."
And it's not just their daughters that are confronting her with a teaser clip of the season ahead on I Am Cait showing an emotional confrontation between Kris and Caitlyn.
“You’re sensitive and amazing to all these new people in your life. You’re just not so sensitive and amazing to the family you left behind," the Kardashian matriarch tells her ex.
"When you feel like you gave your whole life to somebody and the sum of it all was you were a distraction..."
