In 2016, Khloé Kardashian revealed she felt blind-sighted by her stepdad, Caitlyn Jenner, when she found out about her transition through E! network executives instead of Caitlyn herself.

"[E! network execs] mentioned Bruce had a television show about transitioning, and that's the first we heard of it … We felt betrayed because more business people [knew]," she said on Howard Stern's radio show. "We felt so, like, what the f–k! We've been asking you, and why do [business] people know?"

After the radio show, Caitlyn reportedly responded to Khloé with a string of angry texts.

“She can tell me to f–k off all she wants," Khloé said on an episode of Keeping Up With the Kardashians. "I don’t have a relationship with her. I’m done."
