The reality star says she's been told that it's "completely fine" to call Caitlyn by her former name.
Khloe Kardashian admitted that her family is still adjusting to Caitlyn Jenner's gender transition, including calling her by her new name.
"We don't like to say that Bruce is gone per se," the 31-year-old reality star told Australia's The Project on Thursday. "We, my sisters and I, we will call Caitlyn 'Bruce' and we've been told that's completely fine."

Khloe goes on to explain that Caitlyn herself has accepted that she may sometimes still be referred to by her former name, Bruce Jenner.
"And she has told us, we are allowed to call her any name we want to. Because on the phone, when she calls me, it's the same voice as Bruce," Khloe continued. "And if I'm not physically with her, it's hard to remember in the moment that I'm talking to Caitlyn, if that makes sense."
While the youngest Kardashian sister was quick to call Caitlyn's journey "a beautiful thing," she did admit that it's been a trying time for her and her siblings.
"I think what people don't seem to remember is that, this is our real lives and that a lot of these things we are experiencing in real time," Khloe said. "I think there was a hard time for the entire family, that we were all transitioning with her, but in front of an audience, I think that's not really the normal way to go about it, you know."

She added that there were a lot of "raw emotions" during Caitlyn's transition, but was happy to report that the family "got through it."
"So we are just happy for her," Khloe said of the former 65-year-old Olympian. "We just want her to be happy."

In a preview of I Am Cait, Caitlyn admits to Kim Kardashian that she's having trouble with her "feminine" voice.
"Women cannot relate to the whole 'voice' thing. They don't see it as being that important," she explained. "It is that important. Not only just for you to speak, and order and do all that kind of stuff, but it's very important for your soul that you're feeling good about that."
