Meanwhile, Caitlyn's daughter Kendall Jenner has admitted she is struggling to find ways to bond with her parent as they no longer do "boyish" things together.
The 20-year-old model told her sister Kylie Jenner: "I miss doing stuff with dad that we used to always do.
"Like the boyish things, like dirt-biking and, I don't know, the adventurous things. I just feel like you guys bond so well because you're super into make-up and I'm obviously not as into make-up as you."
In a sneak peak for the next episode of Keeping Up With the Kardashians, Kylie, 18, replied: "Maybe get your nails done together. You should just talk to her."
However, Kendall admitted she was worried about hurting Caitlyn's feelings and doesn't want to upset her dad.
She said: "I'm so happy that my dad is at a place where she's really happy and she's really comfortable with everything, and I don't wanna be the one to kind of get in the way of that."
