The Keeping Up With The Kardashians star, 35, has been keeping a very low profile since welcoming her third child last month, but over the weekend she returned to Instagram with a new photo.
Showing herself standing in a pretty impressive (and organised!) wardrobe, the reality star is seen with a waist-training corset strapped on. "Getting it right, getting it tight… with my waist shaper!" she said.
Kourtney's not the first member of the Kardashian clan to try waist training.
Both Kim, 34, and Khloe, 30, have previously shared snaps of themselves with the device strapped around their waist. Kim actually has two! One in purple and one in blue!
Kourtney's kept out of the public eye since welcoming son Reign Aston Disick on Sunday, 14 December, the same day as first child Mason's fifth birthday! We've seen Scott out and about with her family and hosting parties in Vegas, but so far Kourtney's kept well away from the cameras.
While she was waist training in LA, her younger sister Kim was down in Arizona at the Super Bowl. Kim jetted off to Glendale with husband Kanye West and their daughter North, one, for the biggest date in the sports calendar.
As well as watching the big game, Kim was also on hand to support Kanye at a pre-Super Bowl concert where he made a surprise appearance midway through headliner Rihanna's set.
