Khloe Kardashian STRIPPED DOWN for sis Kourtney's Poosh brand and its Instagram promotion of the lifestyle brand founder's "slow jams" playlist.

Not sure why Khloe's doing this instead of Kourtney but some fans are speculating she wanted more attention from baby daddy Tristan Thompson who commented on another sexy selfie just a day before.

Khlo posted a show, showing off her extra-large lips and dip-dyed fingernails with the caption, "I'm not sure where this peace sign thing came from." Uhhh ... well Tristan remarked: "Perfection [heart eyes emoji]," in a now deleted comment.


Meanwhile, in other Kardashian promotions ... Kylie Jenner is launching a collab with Balmain! The beauty brand billionaire will work with family friend and Balmain creative director Olivier Rousteing on a limited edition pallette that will appear on the fashion house's Spring 2020 runway. The Kylie x Balmain products will be available the same day, Sept. 27, and will no doubt sell out quickly!
