Last week’s episode was relatively calm by Real Housewives of Atlanta standards, but as Sheree Whitfield says in this sneak peek, “It’s going down at Kim’s baby shower.”

However, before we get to the baby shower showdown (by the way, why do our beloved housewives always fight at functions meant to celebrate children? Joey Giudice’s christening anyone?), let’s see if we can understand why Phaedra Parks’ hubby Apollo was in such a bad mood.

According to this sneak peek, Apollo can’t quite shake his criminal past, and is still getting pulled over by the police, despite doing nothing wrong.

Now for the baby shower drama. We aren’t really sure why Phaedra is under the impression that Cynthia Bailey’s husband Peter dislikes her (nor do we understand why she chose to bring up their beef at a baby shower), but everything just escalates from there.

So far, the highlights from this fight include Apollo calling Peter old and the sheer look of disgust on Kroy’s face. Watch it all go down below!
