The 17-year-old model spoke out about her 36-year-old sister in an interview at Bellami Beauty Bar in West Hollywood earlier this week, reported Ace Showbiz.
"Kourt is actually doing great. We're sisters, we always stick together," she said.
While Kylie was at the beauty event, she said that her older sisters were having dinner together.
"I wasn't (there). I didn't even get the invite. They were all in white, I know," she explained.
"I'm missing out. I'm trying to pretend like I was there (right now). No, but um, no it was an older sister night," she added.
