It feels hard to remember a time when we weren’t keeping up with the Kardashian-Jenners and every second of their waking day wasn’t broadcast to us by most members of the family.

But there was an era – 15 seasons ago, in fact – where the exploits of Kim, Kourtney, Khloe, Kendall and Kylie were just a bunch of unpublished selfie on their iPhones.

And the youngest of the brood – Kendall and Kylie – took a trip down memory lane yesterday to 2007; a time when a filler was just the middle bit of a sandwich to them.

Kendall posted the before and after pics of the sisters and captioned them: “My one and only” and “Season 1 – Season 15” with a load of laughing face emojis.

She then put up some pics of the girls in what looks like a joint photoshoot and said “Alien sister @kyliejenner” which we’re sure Kylie will just love.

In response, Kylie then posted footage from five years ago of her own changing look.

Kendall uploaded the pics shortly after Kylie and her boyfriend Travis Scott ’s GQ cover went global.

Kylie was seen with her bum out while draped on to Travis as the pair were interviewed for the monthly men’s magazine.

In the mag, fans were treated to an enthralling interview in which Kylie insisted that despite being the cover story on the international publication, they weren’t really about the fame.
