Whoa! The truth comes out!

Kylie Jenner reveals her best friend Jordyn Woods "f'd up" in the new trailer for an upcoming episode of Keeping Up With the Kardashians. After Woods hooked up with Khloe's baby daddy Tristan Thompson, breaking up their relationship (as if his previous cheating scandal didn't already put their relationship on shaky ground), Kylie had a decision to make -- keeping Jordyn as her BFF or kick her to the curb.

Kylie's mom Kris told her daughter, "For you and Jordyn, it’s like a divorce." And Kylie reassures Khloe, "Just know, I love you."

As it turns out, the family stuck together -- Kylie ditched Jordyn and Khloe ditched Tristan and the KarJenner clan is still intact. Watch the mid-season trailer, though, and see how the drama plays out ... it's INTENSE.
