Khloe Kardashian thinks Kourtney Kardashian was a "b***h" during her relationship with French Montana.
The 'Keeping Up With The Kardashians' stars - who were recently featured feuding over Khloe's decision to travel to South Africa with her now ex-boyfriend on an episode of their spin-off show 'Kourtney & Khloe Take The Hamptons' - confessed the relationship caused a lot of tension between them.
The siblings even stopped speaking after Khloe decided to leave their summer home in the Hamptons just one day after arriving in order to go on the romantic vacation with the 'Don't Panic' hitmaker.
Khloe told HollywoodLife.com: "She was so mad at me. She was such a b*tch about the situation.
"She wouldn't talk to me."
Kourtney confessed that although the pair have now split up, she regretted her decision to fall out with Khloe, 30, after the show aired as she could see how much her younger sister enjoyed the trip.
She explained: "It makes you want to be there because it looks like they're having so much fun so I'm not as mad."
The 35-year-old brunette beauty also admitted that the latest series of their show - which premiered earlier this week - features even more fights between the pair, who found themselves "clashing" a lot during filming.
She said: "There's definitely some fights. I feel like out of all the seasons that Khloe and I have filmed together, we definitely were clashing the most on this season. Khloe just wasn't in a great mood. There was a lot emotionally going on."
Khloe added: "I felt like everything was what Kourtney wanted to do. I didn't get a lot of me time. I just didn't get those opportunities. Nothing is going in my favour here."
