"My family's filled with people that do pretty important things," Kirby continues. "My twin sister Kendall models, Kourtney keeps having babies, Khloe's tall, Kylie makes lipsticks, mom does business, my sister Kimberly is practicing to be a lawyer. And I guess I do some pretty fun things too."
"I'm an amateur model, I like to rollerblade. I'm 24 years old and I guess it's just time for me to start pulling my own weight and help out with the family business," he adds.
Kirby even shares a KUWTK confessional with big sister Kim.
"You're the best kept secret of our generation," Kim tells her brother. Aww!
