You Won't Believe That These Famous Co-Stars Didn't Get Along in Real Life

More often than not, co-stars describe each other as second family. Some of them even end up falling in love and living happily ever after. Other times, however, their relationships can actually be quite rocky when the cameras stop rolling, and nobody knows it. Co-star feuds are some of Hollywood's best-kept secrets, but when actors finally spill about how they really feel when it comes to their actor counterparts on set, that is when things get interesting and, of course, dramatic. From celebs who ran away in fear after kissing their co-star (Yikes!) to the ones who ended up leaving the show mid-season to avoid ever speaking again, these co-stars ahead reportedly did not get along behind the scenes. With the amount of drama here, you're going to want some popcorn, your most comfortable sweatpants, and a cozy blanket to properly take it all in.
