Opening up to her I'm A Celebrity... Khloe was not happy with how Caitlyn portrayed her mother, Kris Jenner, in the book, and she was vocal about her feelings. I raised Khloe since she was five years old.
Cailtyn has also been pictured with Kourtney, Kim, Kendall, and Kylie in recent months.
Sophia Hutchins was unimpressed when the Good Morning Britain host pressed her about her connection with the reality star during a live television broadcast, asking her to "categorise" their association and quizzing her about whether there was any "hanky panky".
"Do you think she's more thinking about herself rather than you?" asked another celebrity. "She was supportive of you coming out bc she doesn't support you throwing her mom under a bus".
According to Caitlyn, she hasn't spoken to her stepdaughter Khloé Kardashian in more than five years.
Viewers watching the show, however, were taken aback by Jenner's apparent cluelessness, and offered their best guesses about what might be at the root of friction between the two.
Khloe is yet to respond to Caitlyn's comments.
During an interview with ITV's Lorraine, Khloé said, "No, I don't think that affects anything with Caitlyn".
The topic came up, reports the Mail, when a fellow castaway asked Jenner whether she came out as trans to certain people first.
Caitlyn Jenner is revealing a MAJOR source of tension in her family - we knew things weren't great, but even we are surprised it's gotten this bad.
She shared a video of her former step father waking up her campmates by shouting "rise and shine" - which many fans had suspected was a nod to Kylie.
