In this sneak peek at Sunday's Keeping Up With the Kardashians, the 18-year-old teaches Caitlyn how to be "camera ready."
"I don't know what my look is," Caitlyn, 66, says, soliciting Kylie for some advice as the two pose in the mirror together, and bond over their love of style and makeup.
"I feel like my dad and I get along more now, because we like to do the same things," Kylie shares. "I'll say random stuff like, 'I'm about to get a spray tan,' and she'll be like, 'How are spray tans? Are they good? I think I wanna try one.'"
While Kylie and Caitlyn's relationship seems to have developed over their mutual love for fashion, it seems that Kendall feels a bit left out in the cold.
"I miss, like, doing stuff with dad that we used to always do, like the boyish things like dirt biking and, I don't know, adventurous things," the 20-year-old model shares with her sister in this clip from the upcoming episode.
"I just feel like you guys bond so well because, like, you're super into makeup," Kendall adds, "and I'm obviously not as into makeup as you."
"Maybe get your nails done together," Kylie suggests, but for Kendall, the concern is hurting Caitlyn's feelings.
"I'm so happy that my dad is at a place where she's really happy and she's comfortable with everything," Kendall explains. "I don't want to be the one to kind of get in the way of that."
