Have you been feeling in the mood lately for another classic Glee slap? If so, you're in luck  and FYI, you probably also need a little more happiness in your life  as Rachel (Lea Michele) is going to be planting one on recent bestie Santana (Naya Rivera). Get the icepack!

We've known for some time that Season 5, Episode 9: "Frenemies" would bring some major Pezberry drama. Rachel and Santana have been mostly conflict-free this season, but that all changes when Rachel invites Santana to a Funny Girl photo shoot, and through a crazy turn of events, Santana ends up landing the role of Rachel's understudy. Insert Rachel pouting here. 

We had heard a rumor that tensions would get so high between the two that things would turn violent. Now, we see in a new promo for the episode that it's Rachel who will be slapping Santana. And since Santana has slapped more than enough people in her day, we're sure Santana will be able to critique Rachel on her execution and give her pointers for next time. 

The promo — set to to the tune of Sara Bareilles's "Brave," which will be sung as a duet by Rachel and Santana — also shows a glimpse at Rachel in her awesome Funny Girl getup, along with Sue (Jane Lynch) telling two mystery people at an apparent audition, "Thank you — I hate you both."

But the part of the promo that has us most concerned is that slap. Will the beloved Pezberry friendship ever recover — and will one of the ladies really be moving out because of the debacle? We're having a hard time being brave about this upcoming plot twist. 

Do you think Rachel is out of line for slapping Santana? And do you think one of them will really move out?
