And you've probably seen that they modeled for Kim Kardashian's shapewear line, Skims, last year.
They were shot by photographer Donna Trope and slayed the whole shoot:
Like, of course they did, because it's them.
Well now, we got to see some behind-the-scenes shots of them from the shoot, now that Megan shared it on her Instagram on Monday.
The first pic is them posing face-to-face, the second is Kourtney straddling Megan on a toilet, and the third is them just modeling like rent is due. Megan captioned the IG "BTS of my skims shoot with Kourtney. Should we start an OnlyFans?"
Obviously, a bunch of people in the comments replied yes.
