Kailyn Lowry may be happily engaged now, but during the filming of Teen Mom 2 Season 3, she was caught in a messy ordeal with her baby daddy, Jo Rivera.

In a sneak peek clip from tonight’s premiere, her ex comes over to chat about the new girl in his life, and Kail doesn’t waste any time getting into the thick of it.

As soon as they sit down, she asks, “What’s the deal with this girl, Vee? Is it serious or what?” Quickly, Jo says that it hasn’t gotten serious at this point because he doesn’t “really have time for a girlfriend right now.”

The conversation heats up when Kailyn asks if this new girl knows that they were having sex, and Jo shoots back that hooking up was a mistake!

“We’re doing such a good job co-parenting and getting along, and I think we just took a step to the left a little bit,” he claims. “I think we can both agree that it was a mistake.”

And that’s not the only mistake of the night — Kailyn does not approve of V being around Issac.

”I don’t want this girl around my son,” she says before starting to cry and asking him to leave. “There’s no reason for her to be playing mom.”

Did Kailyn overreact or do you think Jo should be upfront with V about their relationship? Check out the heated conversation below and then weigh in below.
