Nothing like a girls' trip to bring out the backlash when your family friend screws you over!

Kim Kardashian, sis Khloe and Khlo's BFF Malika Haqq took to their G Wagon for a girls' trip yesterday amid all the fallout from news that Kylie Jenner's pal Jordyn Woods has been hooking up with Khloe's baby daddy Tristan Thompson. So how to you start out a trip like that? A bucket of Popeyes in the car with milkshakes? Not for these ladies -- they begin by posting a thinly-veiled lip sync video to Kim's Instagram story, mouthing the lyrics to Brandy's "Who Is She 2 U," as Malika looks straight into the camera and sings, "Find your own man." Gee, coincidence?!

Kim wasn't the only Kardashian to take to social media to air her anger over the scandal ... Kourtney posted a cryptic message herself in the form of a topless selfie! Okay, how could this pic have anything to do with Jordyn and Tristan? Well, astute fans point out the diamond snake necklace around Kourt's neck as a symbol for Jordyn -- a SNAKE!
