Popularly known as a performance artist and internet celebrity sensation, Kirby has long been known for his Instagram account where he has been posing as Kendall Jenner’s faux twin brother since 2015.

But while Kirby’s deft impersonation has afforded him a solid following, the Webby award nominee is officially set to appear on an eight-episode series produced and directed by Kendall and Kris Jenner themselves.

“Kirby Jenner,” starring the 24-year-old performance artist himself, will chronicle the “daily life of Kirby Jenner, the fraternal twin brother of Kendall” and “features Kirby’s interactions with all members of his blended family, including sisters Kourtney, Kim, Khloé, Kendall and Kylie,” as per Quibi.

Executive producers Kendall and Kris will be making a cameo in some episodes of the upcoming series along with the Kardashian sisters Khloe, Kourtney, and Kim. Guest appearances such as Ray Romano, Ted Danson, and Beverly D’Angelo are also slated to emerge in the show.

Meanwhile in an interview with CNN, Kirby dished on some details prior to the show’s launch while maintaining his characterization.

"It actually wasn't my decision at all. It was actually my mom's idea (to do the show)," Kirby said of Kendall’s actual mom, Kris Jenner. "(Kris) mentioned something about a guy named Quibi and how he wanted to do a reality show with me and I was like, 'Whoa, there's a guy named Quibi?'"

The performance artist added that upon hearing the news, he felt very “intrigued,” and initially thought that "Quibi" was the producer.

“I was so intrigued and she was like, 'No, the network is called Quibi, the guy's name is Jeffrey Katzenberg. I Googled Jeffrey Katzenberg and I was floored to learn that's the guy that made 'Shrek'!" he shared.

Talking about working on the show with Kris, Kirby stated that he feels “really blessed” to have someone like her and says that his “mom,” Kris, is the “one of the best executive producers in the world.”

“She executive produces my entire life. She is the executive producer of my home, where I live with her, she executive produces most of my meals and a lot of my travel. I mean, she's the best," he gushed.

“Kirby Jenner” will premiere this Sunday (May 31) on Quibi. As per Kirby, his reality show will feature “a little bit of everything” such as fashion and modeling and even pyrotechnics,all while showing the world what he does behind closed doors.
