Don't you hate when your baby daddy is dating a "hoodrat" named Vee? Poor Kailyn Lowry is having a hard time coming to terms with Jo Rivera's new girlfriend (you know, that chick he dry-humped in his debut music video?), especially because she's hanging out with Baby Isaac non-stop!

In fact, when Vee writes Kailyn a kind-hearted letter to break the ice, Kail has a total breakdown, flips her hair around in a rage, and kicks Jo out of the house. Dang, girl, we know Vee's dye-job is questionable, but there's no reason to get feisty! Then again, it's understandable that Kailyn can't get on board with Jo's adventures in Lady Land. Ch-ch-changes, guys — David Bowie was right!

In other news, Kailyn and Javi are getting closer than ever — despite the fact that she wants to keep things casual. All we have to say is "DHSJADHSJAKHDJSKA" (that was our fingers freaking out all over the keyboard). These two are slaying us with their adorableness! In fact, Kailyn invites Javi to Isaac's emotional 2nd birthday party, where he and Jo have their first meet and greet. Awkward!

Hopefully Kailyn will lighten up when it comes to Jo's dating life, but she has some legit concerns … like what if Isaac spends too much time around Vee, grows his hair out, and starts sporting a ponytail bump?
