So many of us had no clue about the glamorous life of Kirby Jenner.
He's the fraternal twin of Kendall Jenner.
He's an amateur model, and his amazing and fun life with his sisters is documented on his Instagram page.
It's a parody account that now has 439,000 followers.
As Kirby points out, he was cropped out of all the ultrasound pictures, so it was quite a surprise to his mother, Kris Jenner, when he popped out 22-hours after Kendall.
