If you watch Keeping Up with the Kardashians online, you know Kourtney stripped down for a fully nude photo shoot Sunday night.
If you don't watch it ... consider this your highlight reel!
This isn't the first time we've seen a Kourtney Kardashian nude photo shoot, or even gone behind the scenes of one via KUWTK.
But it was a noteworthy one just the same.
Don't believe us? Check out the images below of the 36-year-old mother of three (!) posing in the buff, on the ground and standing up.
Seriously, could her curves be any more insane?!
Photographer Brian Bowen Smith told her flat out that "if you're not blown away by your picture, then it means we didn't do it right.”
Kourtney then confessed her one major insecurity.
"The only thing is I feel like my ass like disappeared when I lost weight," the realty star lamented. "We need to plump it up."
Do we, though? It's awfully hard to fix perfection.
Kylie Jenner, who was present to watch her half-sister bare all, has big shoes to fill if and when she decides to go down this road ...
Like Poetry in Motion
Kourtney Kardashian has posed naked on Keeping Up with the Kardashians before, as that's kind of what she does for a living sometimes ... but that doesn't make the January 2016 episode in which she did so any less magnificent.
The Bottom Line
In more ways than one, if you know what we mean. We mean Kourtney showing off her bare bottom helps rake in the dollars, improving the financial bottom line considerably for her family.
Work it Out!
Kourt said she feels like she's in her workout class. NOTE: We need to sign up for that workout class.
Kourtney on Top
Kourtney Kardashian may not be wearing a top in this screen grab from Keeping Up with the Kardashians, but she is on top of the world in our book.
Kim Kardashian gets all the publicity, but Kourtney is pure perfection.
