KIM Kardashian and sister Kourtney are locked in a new war behind the scenes of their reality show, friends claim.

The sisters have fallen out again, say insiders – with oldest sibling Kourtney, 45, telling friends she thinks Kim, 43, is “talking behind her back”.

“Kourtney and Kim barely speak now if it’s not on camera for the show,” an insider claims.

“Since Kourtney had her new𝐛𝐨𝐫𝐧 Rocky she’s been so busy – she’s got work, breastfeeding, looking after her kids and stepkids and is perfectly happy to stay at home and be in her own little bubble,” says the insider.

“She doesn’t have time to go to parties with Kim or spend hours with her family and friends. She was really hurt recently when she read the story about how she’s cutting off her old friends.

“I think that Kourt thinks it’s people in Kim’s circle behind the rumours – when Kim doesn’t have a man, she’s always stirring up family drama.

“She was targeting Khloe a few months back and now it’s Kourt’s turn again.”

The Sun has contacted their reps for comment.

The Kardashians viewers watched in recent episodes as Kim, who has four kids with ex Kanye West, and Khloe, who has two with her ex Tristan Thompson, clashed over everything from parenting styles to using their phones on a family trip.

Kim lashed out at her sister for ‘not being in the moment’ and always Facetiming her 𝘤𝘩𝘪𝘭𝘥ren on a family ski trip.

The sisters share a fraught relationship, with their last on-air row taking place in September last year.

During the Season 4 premiere of The Kardashians on Hulu, Kim claimed during an argument that all of Kourtney’s friends had been complaining about her behavior in a group chat labeled “Not Kourtney.”

Kourtney hit out at the accusations in a scathing response on Instagram.

She was quick to clear up the rumours, responding: “No the members of that chat are namely Kim, Khloe, Kendall and Kylie. Case closed,” with a detective emoji.

Kim previously broke down crying on screen, asking her sister “why you hate me so much.”

She went on, claiming: “You have a serious vendetta. You hate us. You are a different person. We all talk about it.”

Kourtney hit back: “Because I don’t need you guys anymore. I don’t need to be a part of it.”

She then accused her sister of being “a narcissist,” saying: “It is all about you. Anything you do, it’s about you and how it looks to the world about you.”
