The image, which is part of a nude portrait series by photographer Brian Bowen Smith, simply shows the 36-year-old reality star’s toned behind, her long flowing hair, and just a hint of side-boob.
The mother of three used a dark moon emoji to caption the artistic shot.
Meanwhile, according to Us Weekly, the KUWTK star and Canadian pop star Justin Bieber, 21, have been seeing each other in secret for the last four months.
“Justin and Kourtney have been hooking up since late August, early September,” a source told Us Weekly.
Added another source, the “Sorry” singer has already “bragged” to his friends about his tryst with the mom of three.
“Justin started hanging out with Kourtney alone because she started going out more,” the second source said.
