How to become besties with the Kardashians, according to someone who's done it.

Ever wondered how to become besties with the Kardashians? Just ask Kirby Jenner.

He’s the newest member of the infamous celebrity clan that you’ve probably never seen. Until now.

He’s so close with the family that he even starred in the remake of their reality TV show Keeping Up With The Kardashians‘ opening credits to mark the 10th anniversary.

Uh oh… #Season14 #MyFirstSeason #kuwtk

He could even have a starring role in Season 14 (Yes, it really has been going on that long.)

That said, the honour didn’t come easy. Or naturally. Or even, you know, socially acceptably.

In fact, unorthodox is probably the most accurate description.

Listen: How the Kardashians changed TV. Post continues after audio.

You see, Jenner (the newer, not the original) finally gained acceptance into the family by pretending to, err, be part of the family. Kendall Jenner’s fraternal twin brother, to be exact.

How did he prove this? By photoshopping himself into all her photos and sharing them on his own Instagram account.

We’re not going to lie, the results are pretty impressive.

Kendall and I got invited to what I thought was a Mets baseball game and were told to wear our FANCIEST outfits. It ended up being a swanky museum party with tons of tiny food plates! I think I ate like 40 pigs in a blanket AND got to try fish for the very first time. Also check out my exclusive interview with Yahoo Celebrity where I showed them this pic lol (link in bio) #TryingNewThings #SecurityTookMySword #PokedJenniferLawrenceWithMySwordByAccident #SorryJen #MetGala

Modeling is super fun but inventing clothes is my real passion! This jumpsuit was inspired by the movie “Kangaroo Jack,” features two separate sandwich pockets and is completely flame resistant! Special s/o to Kim for letting me have her old Levi’s to repurpose. Feels good to accomplish something so important and I’m excited to hopefully (fingers crossed!!!) sell them in front of select Subway restaurants across the SoCal area. #FootLongFashion #ActuallyDontMentionThisToKim #HaventTechnicallyAskedForHerOldJeansYet #DenimDrama #SandwichPocket

Been testing out some of my stand up material on the squad and everyone SRSLY loves my sandwich related knock-knock jokes. For instance, Knock Knock / Who’s there? / Lettuce / Lettuce who? / Lettuce in, it’s FREEZING out here!!! Auntie Grace laughed so hard she had to straight up leave the fashion show and cool down at a Wetzel’s Pretzels for 10 minutes LOL. #KnockKnock #WhosThere #KirbyTheComedian #KirbyTheComedianWho #KirbyTheComedianComingAtYa #LOL #TheNextCarrotTop

Had kind of a late night trying to glue Khloe’s aquarium back together (which I broke with my new bow and arrow haha oops) and I kept falling asleep on set smdh. Our photographer, Patricia, kept throwing candy into my mouth to wake me up but I srsly almost choked on one so she just gave up and decided that me sleeping made the pic more artistic hahaha. #DontTellKhloeIBrokeHerAquarium #Shouldn’tHaveTypedThat #IDon’tKnowHowToDeleteStuffYet #IAlreadyReplacedTheFishAndSheDefinitelyDoesntRealize

Ever since I got my pet bird, Shannon, we’ve wanted to put together a freakin dope magic show for the squad. But doing magic in front of people is hella scary… so Kim got me and Kanye a Groupon for a magic class and now me and Shannon have been called “the best dinner theater at Dave & Busters” so far!!!!!!! #ThanksKim #ImaChillHarryPotterNow #AlsoAfraidOfBirds #SmokeInhalation

It only took him 690,000 followers and two and a bit years (he first posted in July 2015) to infiltrate the inner circle.

The hilarious team presumed to be behind Kirby’s creation have even done interviews with the likes of Teen Vogue and Love Magazine.

It’s proof that not only does dedication and perseverance pay off, but also that the Kardashian’s clearly have a good sense of humour.
