She captioned the post, "Love is the highest frequency," and the post was set to Astrud Gilberto's rendition of Fly Me to the Moon.

Kourt hasn't been shy about flaunting her frame after welcoming her fourth child, Rocky Thirteen Barker.

Mrs. Barker has not only praised her own body amid her postpartum recovery, but she's also encouraged fellow new moms to follow suit.

Prior to the Lemme mogul's sexy love bomb, Kourt took a trip down memory lane with a look back at her school days.

The reality star shared a throwback pic on IG of "College Kourt," which showed that Kourtney was always about that "poosh" life!
