With so many Kardashians and Jenners in the ubiquitous celebrity family, it can be hard to keep up with all of them properly. So, if you have no idea who I'm talking about when I mention Kendall Jenner's "fraternal twin brother" Kirby, you're totally forgiven — especially since he's a fake relative whose persona only exists on Instagram (for now). Soon, audiences will know a lot more about the mysterious Kardashian-adjacent figure, since he is expanding his reach with Quibi's Keeping Up With the Kardashians spinoff Kirby Jenner.

Kirby Jenner is a performance artist who has been posting on Instagram for more than five years. Per his Instagram bio, he calls himself an "amateur model, lover of all things, and fraternal twin of Kendall Jenner." Of course, Kirby isn't actually related to any of the extended Kardashian family; he photoshops himself into photos with Kendall and her other family members. With more than 1 million Instagram followers, he has built an entire persona around the obviously unreal notion that he's a celebrity sibling.

Now, that persona is going to be the subject of a spinoff series, and the Kardashian-Jenners themselves are involved with it. Kendall and her momager Kris are producing the new series alongside Kirby, the show's star.

According to Deadline, "The celebrity series will chronicle the daily life of Kirby Jenner, who is set to step in front of the camera for the first time." It sounds like the new show will follow in the reality-show footsteps of its big sister series by showcasing Kirby as he interacts with his pseudo-sibling.

"I’m thrilled that Quibi viewers will get an inside look at the life of my twin brother and he’ll finally have the opportunity to shine in this series," Kendall said, apparently jokingly in a statement announcing the new show. Her siblings are expected to also make appearances.

The release date for the show hasn't been announced yet, but Quibi launches April 6, 2020, so Kardashian-Jenner fans will hopefully be able to get to know Kirby better this spring.
